I have 2 wordpress servers running on my site.
One for the domain:
And one for the subdomain:
I tried to change the permanent links on the subdomain and mistakenly put the whole URL as a permalink. After that, the subdomain went down and got "internal error 500".
I'm not even able to access the word press control panel to undo the change. I heard about the .htaccess file, accessed via ftp and there's none, I created one and I'm still getting the error.
Need some help please !!
