DarkerAngel Posted November 17, 2008 Share Posted November 17, 2008 so I think you deleted a page that contained the function... I really don't know how much I can help since I have no idea what your using or what that function is used for (assuming something to do with a message subject) Quote Link to comment https://forums.phpfreaks.com/topic/133049-fatal-error-call-to-undefined-function-get_the_subject_by_id-in-cwampwww/#findComment-691949 Share on other sites More sharing options...
