So, the errors you’ve listed above suggest that some key core files still don’t exist or are otherwise not accessible.
Start by comparing the files on your server to everything under https://core.trac.wordpress.org/browser/tags/5.7/src
Since you’ve already re-uploaded everything, this is the next best way to ensure you have everything and they aren’t just being removed at some point.
If you don’t have all the files, try re-uploading the missing files from a fresh download https://wordpress.org/download/ If they disappear again, contact your hosting provider’s support to ask why.
If the files are all there, make sure permissions on the files are 644 and directories are 755: https://wordpress.org/support/article/changing-file-permissions/
If this all checks out, what version of PHP are you currently running?
All the files are in there and the permissions are correct. I am running on php version 7.2. I cant run it on 7.4 because i am using another website software on my host which is not compatible with 7.4
I again tried to install the new core files but i keep getting the error
Hiya Jesse,
So a few things stuck out to me when looking at your logs, most specifically the words “Backend fatal error”, are you running some kind of split setup, with the frontend and backend in different locations?
I’m also curious, as you mentioned the site working until you enabled 3 plugins, are you enabling the same 3 plugins every time, if so could you share what those plugins are?
And as a final question, when you have no plugins enabled, are you able to go to the Tools > Site Health page, and get us the debug information form the “Info” tab there?
