Today I made the big mistake of upgrading from PLESK 7.2.0 to the newly released PLESK 7.5.0. Prior to upgrading I backed up my sites with the PLESK backup utility and now that I try to restore the sites PLESK 7.5.0 tells me that the backup files are not a valid file for PLESK 7.5.0. I have never had any real problems with my previous upgrades but this upgrade didn't work first time round so I had to start from the begining with a fresh install and now the backup files aren't recognised. Can anybody offer any advice? Regards Nick Smith Bristol U.K.
