When I put wysiwyg fields under a tab, on first load it looks normal. But when I switch tabs in post editor, all wysiwyg buttons disappear and the textarea is not writable anymore. Sometimes page refresh helps but most times it does not.
As soon as I remove the tabs, all wysiwyg fields start working perfectly again. This can be reproduced 100%.
I even tested with all other plugins deactivated to make sure that there is no interference.
Can you help? I actually need tab functionality....
