I recently took on a new project and I was going to do some simple edits, but when this company handed the site over to me – I was told they “touched it and now it won’t work.” I have no actual clue what they did to make the site incompatible somewhere. Someone mentioned maybe downloading the elementor plug in, and I thought that made it incompatible, but I removed it and I am still having issues. Here are a few codes it is throwing to me. I just don’t know what direction to go anymore.

Looks like an extension potentially. Remove all extensions 1 by 1 and see if the sure works then reactivate one at a time.

There is a link in there mentioning the deprecated extension. Scroll to this section “1. You’re Using an Outdated Version of WordPress with PHP 7”
