Hi Vladimir – we may have made some progress in identifying the issue:
The following scenarios are with a GeneratePress Pro child theme enabled.
When the Author user role has its Post Edit access set to Prohibit and specific post IDs are included, the event calendar series update fails.
When the Author user role has its Post Edit access set to Allow and no specific post IDs are included, the calendar series update succeeds.
When the Author user role has its Post Edit access set to Prohibit, specific post IDs are included, and the ure_manage_options capability is enabled, then the event calendar series update succeeds.
So what we’re trying to get to work is:
The Author user role has its Post Edit access set to Prohibit and specific post IDs are included and the ure_manage_options capability is not enabled for the Author role.
