What does 'Site administration' -> 'Notifications' show as your Moodle version please:
Oops, looks like I copied the wrong version number above.
Hi Craig,
The release build you are using - 20140515 - is version 2014051200.01 and not 2014051201.07 as you reported. Therefore, please update your M2.7 to one dated on or after 20140703 being version 2014051200.10. Unfortunately there is no correlation between release and version so it can be tricky matching the release build dates to version.
Cheers,
Gareth
Downgraded the required version slightly in the last update, so go ahead and update to that version, it should not have any issues with version check mismatching.
