Template update failure - unaccessible website

[peppefava]

Hi to all,

Right after updating to the latest Joomla! 3 version, I also tried to update the current template as well as 3 plugins.
The website was working after updating Joomla, at least this is what I guess since I was able to launch the template and plugin update from the administrator control panel.
A couple of minutes after launching those last updates, the administrator page turned white and from then on I have not been able to access the website nor the administrator page anymore.

This is the website address www.icdassisinicolaamore.edu.it hosted on Aruba/Linux.

The template owner suggested me to rename the following folders, but it didn't work
plugins/content/ipapagebreak
plugins/content/ipavote
plugins/system/ipatinymce
plugins/system/italiapa


What else should I do?
Thank you so much.
Regards.

UPDATE: I got support from Aruba and they suggested me to switch to a newer version of PHP (I was running 7.4) and there was a small progress: now I can login to administrator control panel as I can see its main page, but still I cannot operate with it as each page I try to load inside the control panel itself shows white.
I tried to switch to PHP 8.0 then 8.1 then 8.2 always with the same result.
I also tried to switch allow_url_fopen to ON, as it was OFF, but the problem persists, so I switched back to OFF.

Welcome to Joomla forum!

You probably have non-core extensions (Components, plugins, modules or templates) that are not compatible with PHP 8.0.

To locate the issue you need to switch on Joomla's Error Reporting + Debug System

In the administrator back-end: System > Global Configuration >
[System] tab: "Debug System" -> set to Yes
[Server[ tab: "Error Reporting" -> set to Maximum

or in configuration.php change the following variables to

Code: Select all

public $debug = '1';
public $error_reporting = 'maximum';

I don't believe J! 3.10.12 will work with later PHP than 8.1.

For your 3.10.12 site, for now, stick with 8.0 or 8.1 (with a view to migrate to 4.x) and you need to also consider the ongoing useful life of your 3.x extensions.
