delivered the opinion of the court:
At issue in this case is whether the parties’ agreement to extend the time for filing a posttrial motion validates an untimely motion requesting such an extension. We conclude that this type of agreement, on its own, does not allow the trial court to retain jurisdiction over the case. Correspondingly, plaintiff failed to timely file a notice of appeal, and we therefore dismiss this appeal for lack of jurisdiction.
I. BACKGROUND
On April 23, 2002, plaintiff, Jody Ann Lowenthal, brought a negligence action against defendant, James T. McDonald, to recover for personal injuries she allegedly sustained in a car accident. Plaintiff filed an amended complaint on August 1, 2002, and the case was tried before a jury beginning on August 2, 2004. On August 5, 2004, the jury returned a verdict in defendant’s favor, and a judgment was entered on the verdict that day.
On August 31, 2004, plaintiff submitted a motion to extend the time to file a posttrial motion. The trial court granted plaintiffs motion on September 3, 2004, and she was given until October 4, 2004, to file the posttrial motion. On October 1, 2004, the parties’ counsel had a telephone conversation in which defendant’s attorney said that he did not object to plaintiff obtaining additional time to file her post-trial motion. On October 4, 2004, plaintiff faxed the trial court a second motion to extend the time for filing a posttrial motion. The following day, the trial court issued an order stating that plaintiff had not “filed a motion for this Court to act upon,” because the motion did not comply with local court rules and had not been filed with the clerk. The order additionally stated that plaintiffs reason for requesting an extension, to comply with initial deadlines in federal court cases, was inadequate.
In spite of this ruling, on October 13, 2004, the trial court “entered” plaintiffs second motion to extend the time for filing a posttrial motion. It held a hearing on the motion on October 28, 2004. At the hearing, defendant argued that the trial court lacked jurisdiction to extend the filing deadline, because plaintiff failed to obtain an extension before the previous extension had expired. The trial court disagreed and granted plaintiffs motion; plaintiff was given leave to file a posttrial motion by November 25, 2004.
Plaintiff filed her posttrial motion on November 29, 2004. 1 She argued that the trial court erred by allowing photographs of the vehicles without expert causation testimony; that a juror was improperly dismissed; and that defendant’s closing argument was so inflammatory as to warrant reversal. Defendant’s response to plaintiffs motion reasserted his jurisdictional argument, in addition to asserting that the substance of the motion lacked merit. The trial court denied plaintiffs posttrial motion on January 20, 2005, and she filed a notice of appeal on February 16, 2005.
II. ANALYSIS
Defendant argues that plaintiffs failure to timely obtain an order for a second extension of time in which to file her posttrial motion deprived the trial court of jurisdiction to grant the October 28, 2004, extension. Whether the trial court had subject matter jurisdiction to grant this extension is a question of law, which we review de novo. See In re Marriage of Miller,
Section 2 — 1202(c) of the Code of Civil Procedure (Code) (735 ILCS 5/2 — 1202(c) (West 2004)) requires that a posttrial motion “be filed within 30 days after the entry of judgment or the discharge of the jury, if no verdict is reached, or within any further time the court may allow within the 30 days or any extensions thereof.” Thus, for the trial court to extend the time to file a posttrial motion beyond the initial 30-day period, it must enter such an order within the 30-day period or within any period of extension already given. In re Estate of Kunsch,
In Kwak v. St. Anthony De Padua Hospital,
Despite the fact that the plaintiff had filed her motions for extensions within the applicable deadlines, the appellate court held that the trial court was without jurisdiction to hear her motions on March 10, because the plaintiff had neither filed her posttrial motions nor obtained extensions of time in which to file the motions before their deadlines. Kwak,
Similarly, in Trentman, the appellate court held that although the plaintiff had properly obtained nine extensions for filing his posttrial motion and had timely requested a tenth extension, the plaintiff’s failure to either obtain the extension or file the posttrial motion by the deadline deprived the trial court of jurisdiction to address such motions. Trentman,
Here, the judgment was entered on August 5, 2004, and plaintiff timely obtained an extension within the initial 30-day period; the trial court granted plaintiff’s motion for an extension on September 3, 2004. Plaintiff was given until October 4, 2004, to file her posttrial motion. Plaintiff attempted to obtain a second extension by faxing the court a motion for an extension on October 4, 2004, but the trial court determined that the motion was not properly filed with the clerk, violated local court rules, and did not profess an adequate reason for the extension request. Regardless of whether the October 4 motion for an extension was properly filed, it is clear that on October 4, plaintiff had failed to either file her posttrial motion or obtain an extension to file the posttrial motion. Accordingly, the trial court lacked jurisdiction to later grant plaintiff additional time in which to file the motion. See Trentman,
Plaintiff argues that because defendant’s attorney stated in the October 1, 2004, telephone conversation that he did not object to plaintiff obtaining another extension to file her posttrial motion, the trial court had the authority to equitably extend the deadline for filing the posttrial motion. Plaintiff cites only one case, Crescent Electric Supply Co. v. Diamac Electric, Inc., No. 1 — 98—3043 (2000) (unpublished order under Supreme Court Rule 23). Plaintiffs reliance on this case is in error, as Rule 23 orders are not precedential and may not be cited by parties except to support contentions of double jeopardy, res judicata, collateral estoppel, or law of the case. 166 Ill. 2d R. 23(e); People v. Wilder,
Still, we recognize that there is some support for the proposition that the time for filing a posttrial motion can be extended by agreement of the parties. The primary case espousing this principle is Krotke v. Chicago, Rock Island & Pacific R.R. Co.,
The appellate court affirmed the trial court’s decision. Krotke,
“The statute imposing a time limitation within which a party must file his post-trial motion is not inconsistent with the inherent power of courts of general jurisdiction to enter orders modifying or vacating their judgments pursuant to the express consent and agreement of all the interested parties. [Citation.] It was within the discretion of the trial court, at the time the stipulation was presented, and the order of extension entered, to determine that the stipulation was valid and whether the time agreed upon within which to file was reasonable. The time stated in the order clearly was reasonable and plaintiff does not contest the validity of the stipulation. Plaintiff has waived his right to rely on the absolute finality of the judgment as provided in section 68.1(3), and thus is not prejudiced by our holding. He cannot complain of that which he agreed to do.” Krotke,26 Ill. App. 3d at 496 .
On the other hand, our supreme court has stated that lack of subject matter jurisdiction is not subject to waiver and cannot be cured through the parties’ consent. People v. Flowers,
We believe that this reasoning is also applicable to the instant case and, therefore, disagree with Krotke. Plaintiff had until October 4, 2004, to either file a posttrial motion or obtain a second extension of time in which to file the posttrial motion. Because plaintiff failed to do either, the trial court lost jurisdiction to grant plaintiffs motion for a second extension of time. Defendant’s October 1, 2004, agreement that he would not object to plaintiff requesting a second extension of time to file her posttrial motion did not somehow revest the trial court with jurisdiction over the matter or otherwise trump the requirements of section 2 — 1202 of the Code, because defendant did not actively participate in the subsequent proceedings without objection. Instead, at the first opportunity, he objected to the trial court’s jurisdiction over the case, because plaintiff had failed to timely secure an extension.
III. CONCLUSION
Supreme Court Rule 303(a)(1) (155 Ill. 2d R. 303(a)(1)) requires that a notice of appeal be filed within 30 days of the entry of the final judgment, or, if a timely posttrial motion directed against the judgment has been filed, within 30 days after the entry of the order disposing of that motion. The failure to timely file a notice of appeal deprives this court of jurisdiction. See 155 Ill. 2d R. 301; In re Estate of Kunsch,
Appeal dismissed.

Notes
Thanksgiving fell on Thursday, November 25, 2004, and the following day was also a court holiday. Thus, plaintiff filed her posttrial motion on Monday, November 29, 2004, within the time limit of the second extension. See 5 ILCS 70/1.11 (West 2004).
