doson Whenever I installed flagrow extesnion. the url becomes like this example.com/admin#/extensions?nojs=1 and the page shows this. Something went wrong while trying to load the full version of this site.
luceos doson clear the cache. This is described in the update or installation notes of each flagrow extension. This is not a flagrow issue this is a cache invalidation bug in core.
doson I did that php flarum cache:clear & also cleared by browser cache tried to login and i can't log in now :-D https://prnt.sc/jk9nna
luceos doson what extension did you install last? What happens when you enable debug in your config.php and do you use cloudflare?
doson it is solved now. sorry for the late reply. i installed Bazaar & upload. it took 30 minutes to get resolved automatically.
