I read a few posts here, mostly the Resolved ones. I have to add this:
I'm using a theme called Cross Apple to try and create a health database in greek. All my pages have this short code among other things like simple text and lists:
[tab title="TestTab1"] Some Text Here[/tab]
[tab title="TestTab2"] More Text Here[/tab]
Now, when I activate the Publicize or Share plugins within Jetpack, the result in all my pages is this:
TestTab1 | TestTab2 | TestTab1 | TestTab2
I get duplicate tabs when I should only get TestTab1 | TestTab2.
When I disable the Publicize AND Share function from Jetpack's options, everything returns to normal. If I enable either one of the two, I get duplicates.
I'll leave them on, so you can go to ihow.gr and see for yourselves. It's in greek and not all the site is ready, but just go to vitamins , choose a letter, choose a vitamin and you'll see the problem with the duplicates.
BTW, latest wordpress + latest Jetpack.
Thank you for your time!
