Hi, I got an internal server error on the admin when I upgraded and now main site not working at http://www.newlifeconference.co.uk/. WordPress is in a subdirectory and strange thing is the site is working at http://www.newlifeconference.co.uk/welcome/ but the main page and admin aren't working.
Have tried going back to 3.5.1 /admin and /includes folders. Have tried deleting .htaccess and adding more memory to php.ini but nothing working so far. Renamed plugin and theme folders to old which just meant the main site also stopped working so struggling to figure out what is going wrong here!
Any help much appreciated!
