I have been updating some of my Joomla websites today with Admin tools and Akeebabackup with no problems but one of them www.westlulworthwi.org.uk is now inaccessible from front or back end. All I get is "500 FOF 3.0 is not installed" Given that I can't even get into the back end what do you suggest? I know that can retrieve a backup using FTF and then use kickstart but is there something else I should try first?
Thanks
