The solution of "uninstalling" the package does resolve the problem. "During the uninstall, the contents of the repository are reverted to the snapshot made immediately prior to the installation of the package." from - https://experienceleague.adobe.com/en/docs/experience-manager-guides/using/instal...

Did you find a solution for outputting only the date (yyyy-MM-dd) on the property lastMod, without the time portion? I have been trying to reach that result with no success so far. The idea would be to have it like this:<url>   <loc>https://www.mysite.com/mypage</loc>   <lastmod>2023-09-11</lastmod>...

Just dealing with the same error here, I came around this article that may be helpful:https://medium.com/@toimrank/aem-post-servlet-e0b07ecc63ac 

I am sorry, I understand it's quite difficult to get any conclusion with little information. But about what you asked:1. Yes, my page is working fine on the authoring instance.2. Yes, I have confirmed the activation of the referenced assets.

Hi @Jörg_Hoh , After doing all the author and publish configuration, and after publishing my home page, which has authored content, I am trying to access it but with no success so far, just a withe page is showing up. Do you have any idea what might be causing it? Thank you!
