Hi Tara.
Thanks for the response.
I've tried that (deleting .htaccess and later uploading a new version) with no result.
I suspect the solution to the problem has something to do with the error I'm getting when I log onto my cpanel ("[Thu Aug 11 21:51:42.411927 2016] [:error] [pid 167345] [client 85.204.195.166:60258] SoftException in Application.cpp:430: Mismatch between target GID (651) and GID (99) of file "/home/jaltewin/public_html/index.php"". But I have no idea what it means.
