Hello,
Ive tried updating our JomSocial website but we got the following error (See below)
We're not able to access the administrator anymore and we cant find anything about this error
Im wondering if its possible to fix this, if it is, how can I do this?

Also we're wondering if perhaps its possible/easier to make a clean installation (Clean Joomla, clean jomsocial) and then when its finished import all the users/posts from the old website
If this is possible, how would we achieve this?

Thanks in advance

Hi,

I can access your site backend without any error.
regarding that error message, that because jomsocial system plugin still inactive. you can manage it from joomla plugins manager.
