[SOLVED] CB Activity prevents user profiles from loading

If you have a custom template for CB Activity then you will need to redo it. Major changes to the template files were done. Compare your changed template files with the defaults to see where you need to make changes.

I have had a similar problem. Certain profiles failed to load, giving the '0 - Call to a member function get() on null' error. I tried unpublishing all activity for a profile that was failing to load but that didn't help. So I tried uninstalling CB Activity plugin and then re-installing it. That worked but all user activities were removed! That is not good, at all but, at least, the problem has gone away. Is there any way that I can retrieve the user activity lists (from the database backup, maybe)? Where are they stored?

CB Activity doesn't delete any of its database data on uninstall. Suggest restoring from a backup, installing latest CB Activity, then switching back to the default CB Activity template in CB Activity > Parameters.
