When I upgraded to PHP 7.4, I was not able to use the front end editor for SPPB pages. I got 503 errors whenever I attempted it.
When i downgraded back to 7.3, I could use the front end editor to edit but I can't save. The save button spools without end, and when I click "close", I get a "Forbidden Access" message.
But your documentation says that 7.4 is recommended.
Can you help?
To compare side by side, I have a cloned website, the only difference is one is on PHP 7.3 and the other on 7.4.
