Hello Ademir,

I have tried to enabled Easysocial - Kunena plugin from your backend, then can't access your backend now.

Can you go to your database > #__extension table > search "EasySocial for Kunena" > set `Enabled` to 0 so that your site will become normal.

By the way, I noticed your Easysocial site is do a lot customization

However, I have tested in my locally all seems work fine. also It looks like your account isn't tied up with any subscriptions on our site. Is there any mistake on our end? Would it be possible for you to contact us at https://crm.stackideas.com and provide us with the order reference and your username so that we can fix this up for you?
