I am currently using the Free Web Hosting Service, Site50.net to host numerous pages which are my Canvas URLs for pulling through into Page Tabs. Naturally, these are not designed for general web use and have been modified to look attractive for Facebook.
I have lost functionality. When I click on Edit App, and at the Settings->'Basic' my screen is blank. I am therefore unable to change any information like the Canvas URL. On the Page which these Apps appear are also affected - as when a user clicks on the Page Tab they simply get an empty box where there ought to be content. I have tried running the Debugger which, when I entered my Site50.net address said that it could not find any information to scrape.
I am unaware of the issue. Furthermore my coding knowledge is somewhat limited to design and implementation.
I look forward to hearing from you.
