Can't edit main page after upgrade to 12.3

Yesterday I made the update from 12.2 to 12.3. Now I can edit the main page, but after saving nothing changed. In the change history, I see always the upgrade version on top. I tried already resetting to an older version and then to edit again, but it didn’t solve the problem.

Does this happen only for the home page? Did you try to clear your browser’s cache after the upgrade to 12.3? Do you have any JavaScript errors in the browser’s JavaScript console (from developer tools)? It would help if you could record your screen while editing and saving the home page to better understand the issue.

For other pages it works.
Cleaning the browser cache and using a different browser did not solve the problem.
Where can I find the JavaScript error log?
Would you need a video of the screen or would screenshots of the steps and results be sufficient?

Usually Right Click + Inspect should open the browser developer tools, which has a Console tab.

Video is best, but screenshots are good too.

Please find attached a PDF with the steps (action/clicks marked in red) incl. the console (sorry, it’s in German).

Is your wiki multilingual? What is the default wiki language and the supported wiki languages? You can get this information from the Localization wiki administration section.

I noticed that the Information tab at the bottom of the page is hidden. Starting with version 12.3 it provides useful information about the locale (language) of the current page, as well as the original (default) page locale and the list of available / missing page translations (if multilingual is on).

The issue in your case is probably the fact that the content you modify is saved in a different page translation (either the original one or the German translation). This could be related to Loading... (fixed with XWIKI-17279: The in-place wiki page edit is always loading the origin… · xwiki/xwiki-platform@b869d92 · GitHub). You can try to apply the fix in your XWiki instance by modifying the page XWiki.InplaceEditing using the object editor.

My wiki is not multilingual, but I had it once set to multilingual to see how it works.
But the issue is related to this.

Localization settings before:

After chainging to multilingual and English, it works. Change history as follows:

When I change back to single language, the modification is not visible anymore.

Where do I find the page XWiki.InplaceEditing? I did not work yet with the object editor.

Thx

Found it and the related code lines.
With the fix it works (changes are visible again).

Just in the history still looks confusing with the “Version coming from extension …” on top.
Is there a way to get rid of that?

You see that only for pages that are part of an extension (it’s the case for the home page, since you didn’t create it), and it’s put on top on purpose so that you can easily rollback to the “factory” version of that extension page. Now, some extension pages, like the home page, are meant to be modified, but I still think it’s useful to be able to rollback to the standard version.
