I have a custom form in the WordPress design template, but internal server errors are displayed when sending. There was no error in the error.log file regarding this submission. I host my website at bluehost and here is my form
<form method = "post" action = "/formprocessing.php ">
In the file "formprocessing.php" I only show some text and forward it to the template file, but it shows the internal server error.
It took a lot of time to sort out this problem, but I still could not figure it out. Your help is greatly appreciated.
