My hoster forced me to upgrade my Wordpress site because it was fairly old. I decided to upgrade to PHP 8.1. It caused issues with the website, so I figured I'd rebuild the whole website since it's a simple website. I deleted all the existing files and uploaded the 5.8.2 WordPress install files. Then I changed all the permissions to 0755. I created a fresh database for the install.

At first, the setup would appear. I would go through the install, but when I clicked install after entering all the database info, I got "There has been a critical error on this website." I recreated the .htaccess file to the default and tried again. Now I get this error just hitting the domain, no more setup screens. The site does redirect to the /wp-admin/setup-config.php file. I don't have a wp-config.php file in the directory, just the sample one. I tried creating a wp-config.php with the correct info, but same error. I also tried adding the debug options, increasing PHP memory, etc. Same error. I don't get any error logs.

Does anyone now how to get an error log or can help with ideas on how to create a fresh WordPress site? I did change the PHP versions to older ones, but that didn't work either.

You need to take a backup of your file ,then fallow the fallowing instruction.

• Rename your plugin one by one and refresh the website. this issue due to the unsupported plugin ,that is installed in your wordpress website.

1- Make a backup copy of the files and from the old database

2- After that, download these files on your PC

3- Install WordPress again

4- Replace the wp-content file with the old one

5- Clean the new database and import the old database through phpMyAdmin
