Upfront not saving changes? click save and endless saving logo?

Hi,
Not sure why it doesnt seem to save the changes. have tried opening other browsers and pages and its working fine (so not a network issue) also checked other sites on the same hosting account with no issues.
For some reason when i click save on some text changes it just doesnt want to save? see
