I installed a plugin that has totally messed up my site big time, to the extent that after several days of banging my head against a brick wall trying to sort it out I have just about given up, save miracles.
All systems, plugins, you name it were all up to date.
I backed up before I activated the plugin so I should have everything I need to be able to restore it to pre disaster days.
I manually backed up and downloaded the back up file from within the site.
As far as I can tell I need to log on to the site and do the restore from within the site.
I can't get in though, so not sure how to go about it at all now.
