For some reason the mapping to the other links was gone. This is what I ended up using:

 $("[dsid$=_link]", $.mobile.activePage).not("[href='']").show();

I did take a look at the source code, but did not change anything in there. No files are marked in blue.

It appears that my mobile device isn't loading the most recent version through the appery app. It has the correct date, but visible changes are not loaded. Closing the app on my iPhone and restarting the app has no effect. And I can't test the app in my browser anyway.

same result

Thank you for this reply. It makes absolute sense, but now I'll get only the Facebook link back.

I can't give a star for this answer, because the result is the same. I'm still having the same problem, thus this topic shouldn't be marked as answered.

The result, not surprisingly, is the same.
