I will fix your wordpress PHP 8 errors and plugin compatibility

WordPress 7.0 and PHP 8.3 removed and deprecated a lot of things that older plugins and themes still rely on. The result is usually one of these:

Fatal error: Uncaught Error: Call to undefined function / method

Deprecated: Creation of dynamic property ... is deprecated

Warning: Trying to access array offset on value of type null

Passing null to parameter of type string is deprecated

A white screen, or an admin area you can no longer log into

I fix the actual cause in the code. Not a workaround, not "disable the plugin", and not hiding the warnings by switching off error reporting.

WHAT YOU GET

Every fatal error, warning and deprecation identified and fixed

Fully working plugin/theme files returned to you, ready to install

A short written report: what was broken, what I changed, and why

Tested against current WordPress and PHP 8.3

WHAT I NEED FROM YOU

A zip of the plugin or theme (or the folder from wp-content)

The exact error message, or your debug.log if you have it

Which WordPress and PHP version you are running

That is genuinely all. No call needed. I work from the code and the error log, and everything stays in writing so you have a clear record of what was changed.
