For others with this issue, it's postbit_lite_background.
Tested and confirmed fix.
Thanks, Hippy.
Quick question for you; I notice that quotes are displayed incorrectly, but I cannot remember the stylevars - I'll search but if you're online and know them by hand could you give a hand?
edit2; seems it's.. gone.. now.. maybe it was just a glitch.. will report back if I spot it again.
Edit3; found another similar glitch, it's on posthistory.php - for viewing the edit history of posts, it's blanked out with white on white, too. Any ideas where this style var is?
