Hello people of codingforums I am having a problem with this "Cannot Modify Header Information". I know that extra blank lines can cause this problem but I just can't see where they are. They're bugging me an if you login
here, you will receive the error. I dont seem to have this error on localhost but on my website I do?
This is the error:
