do you still have the error or do you manage to get the extensions now?
It happened in the past that this kind of error was related to an infra issue on our side, but apparently here I can see the extensions loaded properly.
Catalina-datestamp is the journalized log, the current one is always catalina.out. Note that by default we try to keep it not too verbose so that errors are quickly visible. You have more information there about the logs: https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Logging
The error still persists. When I go to https://extensions.xwiki.org/xwiki/rest/repository/search (a related URL that I found elsewhere in the forum), I get results (at the bottom of this post). Strange, because it worked yesterday. Last thing I did was trying to set up tls for ldap (unsuccessfully).
I have seen the documentation regarding logging, but cannot comprehend it. I come from a “traditional” background, and these tomcat specialities are rather new to me.
Kind regards
[Edit: taking the liberty to remove the answer from extensions.xwiki.org since it’s making the post more difficult to read and doesn’t bring much info]
And when you go in Administration > Extensions, do you see any 404 answer when you look in the network tab, or any error in the browser console?
I expect that you already check catalina.out and didn’t see any error there?
