Hi there,

I had the same problem and couldn't fix this with the workaround mentioned by ssjmec. So I took a look at the code (fortunately it's QML). It's located here:
/opt/foursquare-ov/share/FoursquareOV/qml/Foursquare

I think the problem is on function reload in models/UserSettingsModel.qml, after adding some traces I saw that the settings are requested via xmlhttprequest to foursquare too soon, before the main.hibernate property of the app becomes false (I think this referes to the app not being fully loaded.), after changing some properties in models/Models.qml (delayFirstLoad : true and 60 seconds delay) I still couldn't make this work properly ...

But fortunately I took a look at sheets/CheckInSheet.qml and changed the following:

L104: opacity: wrapper.shareFacebookSet ? 1 : 0.3

and

L121: opacity: wrapper.shareFacebookSet ? 1 : 0.3

So that every time I checkin somewhere I have the option to enable the checkin button right before checking. It's not the best solution (this should just work IMHO) but for me is better than not working at all unless I access the settings page every single time I loaded the app.

Someone with better QML skills might have a better idea on how to fix this for good.

Cheers,
