Mod_speling works in all subdirectories, but does not work in the root directory. mydomain.com/test.php exists, but if I type mydomain.com/Test.php, I get error 404. If I try the same in a subdirectory: mydomain.com/subdirector/test.php exists but, and if I type mydomain.com/subdirector/Test.php, it works fine. I have ISPConfig 22.214.171.124. I tried with and without an .htaccess file.
