I had configured a beautiful tab set, but somehow (while I didn't change anything at all, just refreshed the page) this error appeared:
Warning: in_array(): Wrong datatype for second argument in filepath/wp-ui/wp-ui.php on line 294.
I saw an earlier post on this, but it was mentioned that this bug was fixed in 0.4.1 (I believe). I'm using 0.8 version of the plugin. What did I do that triggered this error?
