My site runs Joomla 6.2.0. I recently upgraded to the latest version of SP Page Builder Pro.

When I go to SP Page Builder Pro > Pages and click Frontend Editor, I get a 404 error for every page. Frontend editing worked before the upgrade, and I expected it to continue working.

The backend editor was suggested as a workaround, but I need to edit pages from the frontend. How can I fix the 404 error?

It has been a while since I tried to edit a frontend page. Also, PHP was updated a few weeks ago but not sure it that was the cause. This is what the 404 page says.
