I have upgraded 2 sites that use Sp Page Builder Pro to Joomla 3.8.10 - and now when I try to create or edit any Joomla menu item I get this error message: Cannot use object of type stdClass as array.
Sp Page builder works fine.
Other sites that do not use Sp Page builder can be upgraded with no problems.
Any idea why this is happening and what i can do to fix it - or are you working on a fix? Thanks,
Syd
