I changed the background and size of my website (with all your advice to 1920*1080) and now my contact form does not work anymore. The content of the website did not change. The settings in the PHP feedback form action are exactly the same as in the previous version of my website and when I upload my old website it still works meaning emails arrive and error message page aswell when tested. Any thoughts ?
yes that does not look good in the code. There is nothing else going on the page than what you see. Very strange since in my old design website with the same content and actions it just works.
Problem solved. The simple search action on the page is not compatible with the PHP FF. So just removed the search function on that page which is not interesting anyway on a contact page. Thanks anyway
