my case is index.php and also dl.php
well my main files from root dir are changed since yesterday as I updated website
website source is here (what should be listed on domain and is not there)
edit:
pushed website files again via FTP and while seem to work for a refresh, now again is not working
all my files were the old ones. It seems like it restored from backups or something like that. Even my custom created folders disappeared and now it works fine.
