Hi,
can some body help me, to remove the extension?
Because it breaks the xwiki installation so, that the normal way over the extension manager don’t work.
On every click of “remove from all wikis” nothing happens and in the log I only see this:

In my case I have luck, using another browser I was able to remove the extension.
But in general how can I remove an extensions, which bricks an installation?

It all depends on the type of extension or what exactly “bricks” means.

The easiest last resort to remove a JAR (or WEBJAR) extension if your wiki is totally unusable is to remove it from <permdir>/extension/repository and restart. But the problem might come from a dependency of the extension and not the extension itself so you will have to check what are those on https://extensions.xwiki.org or directly in the Maven pom.xml file of this extension.

For a XAR it’s more complicated since it’s actually wiki pages imported in the wiki so even if you remove the xar file from the local repository the wiki pages will still be there kicking (except worst this time because you would have no idea they are associated with a specific extension). But normally unless the XAR extension override XWiki.Extensions page you should always be able to uninstall it, at worst if the issue is some rogue javascript breaking everything you can disable it since EM can be used without javascript AFAIK (you will just need to refresh manually from time to time to see the progress move and get uninstall related questions).
