Hey Kaare,
Thanks for updating, I am able to login your backend now. However, can you provide us super admin access so we can better investigate your issue? As you can see in the screenshot, we cannot view EasyBlog backend because of this permission issue. Let us know, thanks.
Hey Kaare,
It seems this plugin is causing the composer to not load properly: System - DJ-jQueryMonster
I have included some of EasyBlog's scripts to protect in the plugin's configuration page so now your composer should be working just fine. Check it out and let us know how it goes, thanks.
