For anyone using the Display Widgets plugin (see also https://s2member.com/kb-article/plugins-that-work-well-with-s2member/ ):
It’s probably best to switch to this one:

Quote: “Yesterday the original Display Widgets plugin was removed from the WordPress plugin repository because the new developers first update (v2.6) automatically connects to a private server to download a GeoLocation Widget (50MB+ zip file of code that extracts directly into the Display Widget plugins directory!!!). With plugins hosted on WordPress.org you can not do that sort of thing!”
I’m using the similar Custom Sidebars plugin, and it seems to work great with s2Member.
