For some reason every profile I visit, including my own, has a message on it multiple times that reads: "Warning: in_array() expects parameter 2 to be array, string given in /www/subeta.net/include/class/achievements.php on line 338 "

Could someone possibly tell me what this is and if they are having the same issue?

What browser are you using?

Chrome. But I seem to have fixed that message on my profile by adding a style tag at the end of my profile coding.

Going to go ahead and lock this thread since it appears the user has found a work around. :)
