Cannot choose theme in my JA Fit Style anymore

After updating T3 and trying to safe a new setting in the Template style / Theme:
-->
cannot select a Theme anymore
there is an error above the settings:

Warning: Invalid argument supplied for foreach() in /home/.sites/152/site9777926/web/plugins/system/t3/includes/depend/t3folderlist.php on line 61 Warning: Invalid argument supplied for foreach() in /home/.sites/152/site9777926/web/plugins/system/t3/includes/depend/t3folderlist.php on line 61

I can use ThemeMagic and safe as a theme - but then the assignment is not possible.
Cannot choose anything - just "Select an Option" visible but nothing selectable.
I can save other settings without problem.
Should be a blue and not red (Default) theme.
Worked until today.

thanks

Hi
its not T3, you updated your Joomla version that is recently released and T3 need to be updated for it, I already shared the report to dev team and they are working on it. I suggest you to restore the site backup, there will be new release soon with bug fixes.

Do not update your site Joomla version without checking all extension and template compatibility. Always take backup of site before updates.
