Tried to move from cloudpanel to cpanel my website and got white screen of death in the admin pages.

Hello,

I tried to move a wordpress website from cloudpanel to cpanel. Copied all files and exported the database with mysql dump. Here is the short version of the issue:

I moved my website here: https://bizman.gr from my old server to a new one.
I tried to make both as similar as possible but the old server is using Ubuntu and Cloudpanel.io and the new one is a centos7.4 cpanel server.

However they both have php 8.0 on them and the php settings are as similar as they can get.

Both have a memory limit of 256Mb, max exec time of 180sec and max_input_vars 10000
Both servers run php v8.0.

So when I transfer the website, make all typical changes in wp-config, the db and user for the db, along with the password, I get my website working just fine, but when I try to log into the backend (wp-admin) I get the White screen of Death and no admin panel.

The only thing I found was in the error log the following errors:

As much as I tried to troubleshoot that issue, It got me nowehere.

Here are some things I tried to do:

• Disabled all plugins. of course that broke the website but did not restore the wp-admin. I was still getting the WSOD there. I had to delete it after that and restore the backup cause I was unable to re-enable the plugins.
• Tried running this command: find . -type d -print0 | xargs -0 chmod 0755 && find . -type f -print0 | xargs -0 chmod 0644 This should fix all the files' righs and properties. I witnesed no change after that.
• I used a brand new htaccess with only the most necessary parts in them like rewrite engine etc.
• Revisited wp-config and wp-settings files. Tried to find any part that had the absolute path in it. I found just one spot at the beginning of wp-config and I fixed that. No change.

Any ideas?
