The host changed the PHP version to 8.1 and now I just have a blank screen on the site

[cecaalteno2]

I left my site unattended due to serious personal problems. The host changed the PHP version to 8.1 and now I just have a blank screen on the site and in the admin. When activating error messages I get the message "0 Attempt to modify property "shortcode_tags" on null" on the admin page. The site is multilanguage

Please, if someone could help me. Thanks

I get the message "0 Attempt to modify property "shortcode_tags" on null" on the admin page

I would guess "shortcode_tags" is not compatible with PHP 8.1 and there may be other out-of-date extensions that require updating including the Joomla core itself, which is 24 months out of date (current version is 3.10.12). However, 3.10 is now EOL. I would advise you to consider migrating to 4.4.x ASAP.

You have left-over templates from Joomla 2.5 such as Bluestork (admin template), Atomic, Beez3, Beez5, Beez20 (2.5 front-end templates). It's best to uninstall these as they don't work in 3.10.x

Can you enable PHP Error Reporting, and Debug, if not through Joomla Adminstrator global config, then in the configuration file directly? Error Reporting and Debug will give further details on the errors and what is specifically causing them.

The FPA report currently states:

Error Reporting: none | Site Debug: false

Turn both of these on. Debug to "true" and Error reporting to "maximum".

Change the php in your Host's cp or try https://stackoverflow.com/questions/125 ... -in-server

You need to set the php to a lower version
