• Upload the file fix.php in your server at the root folder (where the .htaccess and the index.php are)
• Temporarily rename .htaccess to .htaccess.bak (needed only for sites with AdminTools)
• Visit your site's /fix.php (eg https://mydonain.tld/fix.php)
• Delete the fix.php file
• Restore .htaccess.bak to .htaccess (needed only for sites with AdminTools)

And the problem only arose after doing the database repair !? It worked before the repair.

Top, thx! 👍🏼
