Website throwing different page versions?

Alright, so it’s a bit winded post, but bear with me. Here’s the deal:

I updated WordPress to 5.0, and also updated my Woocommerce database, site working fine, no issue. I then installed a plugin to make my speed score on Google speed test better, the plugin is named: leverage browser cache. After doing so, none of the changes I applied to Elementor updated on the live website, I could see the changes in preview mode and in editing mode, but the live page did not reflect them. I disabled the plugin but the website remained the same.

So I wandered into my directory files and accidentally deleted my .htaccess file, no problem, I had a backup, but after restoring the backup my website is now throwing me a ton of errors. Sometimes I get a .PHP line error, others the website shows me an old cached page, and when I apply any changes, they aren’t visible.

When I go to my home page I get a .php error, however when I press CTRL+F5 the website shows just fine. However as soon as I do a normal refresh it’s back to that .php line error. I have no idea what to do.

I’m basically desperate at this point, all my formatting on the elementor pages seems to have been messed up, and I don’t have an older backup to turn to.

I tried deleting all my WordPress files and database, however, upon accessing the website, I still get that darned .php error as if it’s still showing me a cached version of my website, which again, when I press ctrl+f5 it shows fine. I have no idea what’s going on, someone that’s more webdev savvy, can help me out with this?

You have no idea how much I’ll appreciate any help I can get.
