Thank you all for your responses, however I'm still having huge issues updating Joomla from 3.10.12 to 4.4.14
With error reporting set to maximum, it appears the issue is now with my Helix Framework (I am currently running 1.1.3 and shaper_helixultimate 1.1.4). When I try to update to the latest version before upgrading Joomla, it tells me I must be running php 8.1, however Joomla 3.10.12 only runs on 7.4
An error has occurred.
0 Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 8.1.0". You are running 7.4.33.
I'm pulling my hair out!!! Already I've had to completely rebuild 3 of my clients sites from the ground up because of these issues.
