When I login to my acc. the page layout breaks. It reverts to what an old nokia mobile loading the page looks like, I cannot use the comparison slider, it doesn't even load the comparison image. Most of the page features are broken down into their scripts. When I log out everything works fine, can't upload anything. Tried opera, chrome and firefox. Same issue on all, its not my extension as an incognito tab doesn't fix the issue. Any help and suggestion would be much appreciated.
