Microsoft VBScript runtime error '800a005e' 
Invalid use of Null: 'split' 
/Jorrit787/forum/inc_func_common.asp, line 390
This error just came out of nowhere... This is the code block:
	txtBadWordWords = Application(strCookieURL & "STRBADWORDWORDS")
	txtBadWordReplace = Application(strCookieURL & "STRBADWORDREPLACE")
	if fString = "" or IsNull(fString) then fString = " "
	bwords = split(txtBadWordWords, ",")
	breplace = split(txtBadWordReplace, ",")
	for i = 0 to ubound(bwords)
		fString = Replace(fString, bwords(i), breplace(i), 1, -1, 1) 
	next
	chkBadWords = fString
end function
I have no idea why this happened... I didn't modify the file or anything
