hey everyone, hoping someone can help with this issues, been trying to figure it out for a few days now.
doing a basic contact page with processing in the same page and having issues with php processing script. Page throws a white page and after some searching found its a 500 server error. Server has been checked every other page works like it should. When i remove the form processing script no more server error which leads me to something in script is the cause.
