Hello, I wanted to install the update 5.5.2 on 2 different websites. On both sites the frontend was no longer accessible. Only a white page appeared. The backend still worked, but no longer in the page builder area. No page was displayed there. Unfortunately, I didn't remember the error message in the backend.

Both pages are still based on Joomla 3.10.12 with PHP 7.4.33. Could this be the reason?

I have now restored an Akeeba backup for both sites, so that the previous version is now up to date again. I would be grateful for any tips.

Many thanks and best regards, cruisi
