All of the blocks are missing from the customed pages, home page, products listings etc. I just have the blank screen as in the attachement. If I try and add anything I get a helpful box that says 'Errors' in red.
The customer-facing side of things is unaffected.
All I have edited today is the double.css and some images, but this has been rolled out across all of our sites and this in the only one been affected.
I have re-uploaded all of the /admin folder and templates/admin.
Is there anything else I should upload in case there's a corrupt file?
Is there anything I can check in the database to find the error?
