To all users,
We’ve made an infra mistake during a few minutes today. If you tried to access some pages from extensions.xwiki.org during these few minutes, you may have been redirected to Blog categories
This is fixed but the problem is that your browser is now probably caching this redirect and browsers don’t seem to expire cache entries (unless your browser cache is full). If this is happening to you, we’re sorry, and the solution is to clear your browser cache for extensions.xwiki.org.
Thank you and sorry again.
-Vincent on behalf of the Xwiki core dev team
