Latest update kills CB

Just updated all to latest 1 hour ago. I haven't looked into the code yet but CB Profiles come up empty. Apparently a fatal PHP error which I found in the log:

[26-Jul-2021 15:59:27 America/Chicago] PHP Fatal error: Cannot declare class HTML_cbinvitesTab, because the name is already in use in /usr/local/Joomla/components/com_comprofiler/plugin/user/plug_cbinvites/templates/mine/tab.php on line 18

"mine" of course is my modification of an older tab.php which apparently in no longer compatible.
It's great that you allow custom templates on these plugins, but somehow we have to be warned when this will happen. I just finished updating a dozen of my custom templates last month too. Kinda defeats the purpose...

We're gradually updating plugins template systems to just flat PHP files like Joomla template files. We're still working to move all plugins to this new template output. Latest CB Invites stable release rewrote its template files to be just that and is why you're seeing errors.

With CB 3.x they'll be redone as Twig template files ideally and just be Joomla component layouts so you'll more safely be able to override them from Joomla template layout overrides. I apologize for the inconvenience in the meantime.

In the future I highly recommend updating a clone of your site, testing for stability, then updating live site only if the clone appears stable.
