I just setup a fresh joomla 3.6.3 install then installed cobalt 8.725 with media pk 8.85 and template pk 8.1090 enabled cobalt plugins then installed calendar pk 8.10 No other extensions or plugins and I have the same issue Fatal error: Class 'F0FModel' not found in /home1/xxxx/public_html/plugins/system/cobalt/cobalt.php on line 128

This happens when you delete record? Do you have J2Store installed?

But I have fixed it anyway, and I'll upload updates today.

Thanks Sergey the update fixed the issue many thank's

I have same problem in latest version Joomla and Cobalt CCK

Extensions installed: JCE, Akeeba Backup, Coala web contact, Advanced module manager.

Fatal error: Class 'F0FModel' not found in /public_html/plugins/system/cobalt/cobalt.php on line 128

Show me that line? What do you have there?

Sergey Show me that line? What do you have there?

$productModel = F0FModel::getTmpInstance('Products', 'J2StoreModel');

I have not made any changes to that file. I only edit my custom templates.

It is not in my last version. In my last version it is line 130. So, somehow you have outdated plugin.

i have the same problem and i do not have j2store plugin Class 'F0FModel' not found
