Hi,
Thanks for the reply.
I managed to solve the problem (I think) by accessing the site via FTP and renaming the plugins folder in the content to ‘plugins.hold’ and then accessing the admin before renaming again.
Seems to have worked!
Thanks for the info. I’ve checked the instructions and have managed to re-size, but am still having problems with the home paqe thumbnail resolution and can’t find any support info on this?
