I currently see a cannot connect to database message on your website. Can you check to make sure the database still exists in PHPMyAdmin, and the credentials are correct?
So I tried installing it as a multi site with sub directories but once I am done with the process, I am no longer able to access the admin area. it used to work when it had directories
I did all the steps required. There is code for allowing multisite that is to be written in wp.config in the cpanel, there are then a few more lines to be added in this directory, which I did. the next step is to create add another lines of code in the .htaaccess sub directory, which I did. the final step is refreshing the page and then logging in again. it is at this point where I am unable to access my website admin panel. I have tried to reloead severally but it is showing the following error.
HTTP ERROR 508 usually means the entry process limit was exceeded for your site. But I suspect it could also be a rate limiting issue.
You say you only see this after setting up the Multisite, and immediately after you did that? Does it help if you leave the site alone for a while and try again later?
Could you also check the Network log in the developer tools menu in your browser? If you made an error in the URL settings and caused a redirect loop, that could also get you kicked out.
