I have a Problem i want to make a speceal layout for all my video posts. i want to remove the header for that reason and load another css file.
the strange thing is. the css loads just fine and i use the same function "check_if_videopost()" but it not works for the header remove. when i uncomment it then it works fine.
am i doing something wrong or is this maybe not possible to do in the "init" action?
please help
i want to uncomment and the if and else in the remove_header() function i dont want to remove it from every my entire site.
