Hi, does anyone know if it would cause any issues to upgrade PHP to the latest version if we're running Moodle 3.11 with Apache version 2.4.48? We're currently on PHP version 7.4.20
Thanks.
Do you mean to PHP 7.4.27? That should be fine.
If you mean to PHP 8.0 or 8.1 then Moodle 3.11 supports PHP 7.3 or 7.4 only. A search of these forums will show issues with PHP 8.0 or 8.1 (example 1, example 2). Support for these versions can be tracked by watching MDL-70745 and MDL-73424 respectively.
This table of which Moodle versions work with which PHP versions may be useful.
