Good morning,
When I try to update the website to php 8.1 version, the pages appear blank both in the public and in the administrator. Before updating I have put in the error report that the maximum and generated a log where there are several warnings, notice and there is also fatal error on joomlatools. I do not know if it is because of that error that does not work the web to update the version of php or is it something else, if it is not for that I wanted to know how I can fix it and update the version of php.
I attach the error_log file in case it can be of help.
Greetings and thanks
