Zend Errors upgrading from 5.9.4 -

[Clintre]

Ran the upgrade, via the command line and had the same error occurring over and over.

Here is a snippet of it...

Warning: Invalid callback Espo\Core\Log\Handler\EspoRotatingFileHandler::cus tomErrorHandler, cannot access private method Espo\Core\Log\Handler\EspoRotatingFileHandler::cus tomErrorHandler() in /srv/users/<removed>/apps/trteam/public/espo-test/application/Espo/Core/Utils/File/Manager.php on line 265
PHP Warning: Zend OPcache API is restricted by "restrict_api" configuration directive in /srv/users/<removed>/apps/trteam/public/espo-test/application/Espo/Core/Utils/File/Manager.php on line 265

After the update, the system would no longer load. We performed this on a cloned environment first.

Had no problems prior to update.
Tried the rebuild.php as well.

Environment is...

Nginx/Apache PHP-FPM 7.4

Here is the place where an error occurs: https://github.com/espocrm/espocrm/b...nager.php#L265

IT seems that you have some problem with opcache. We used `@` operator to skip an error handling on this function call. But this operator is not allowed in PHP 8.0 so we removed it.

Try this fix https://github.com/espocrm/espocrm/c...690a0218710ec9 (you can replace the whole file). Please let me know if it worked out.
