At the moment, no. But I do have other plugins, so let me create a clean install with just your plug, and I will report back shortly.
Edit.: After adding it to a clean install, everything works as intended.
Added all plugs from previous install, everything works fine.
Possibly upgrading Simple Tabs had it stuck in debug mode?
Or maybe just a random hiccup.
Either way, it looks to be working now. And your new tabs above the editor are pretty slick looking. Thanks for the update.
