Deprecated: The PSR-0 Requests_… class names in the Request library are deprecated

Came across this error after WordPress update? Well, the first time I dealt with one of same nature was when we upgraded our business WordPress to latest version. I have posted about it here & strangely, that is the single post of mine ever got more than couple of likes :)

We are using Elementor and, the stack was the main culprit that was generating maximum errors against the outdated PHP. Having both PHP and Elementor upgraded fixed our issues last time & I didn’t expect anything different this time either.

This time, as soon as I came across the errors once after WordPress upgrade, I asked our hosting partner to upgrade PHP (7.4 => 8.x) for WordPress 6.2.2 and updated Elementor afterwards. That has taken care of the annoying “Deprecated” error messages those were appearing in the admin console (mostly). Please note, while Elementor could be the primary culprit, any other plugin that makes the function calls listed could be the reason for these errors. Update each one of them and see whether the issues persist.
