Maybe it helps when deleting all temporary internet files and empty cache of your browser. This helped me once before. I do not have any other solution except I already have described.

My back office login screen was also white. I could not even fill in my password. I changed the permissions of my cache folder from 755 to 777. I was able to sign in. I changed it back to 755 and it still works. Thanks.

I had same problem. I think this will help. Go to modules and choose payments. Scroll down to currency limitations (valuta beperkingen). Check "customer currency" (klant valuta) under Hipay. Do not choose standard currency of this shop! This will solve the currency issue.
