Otherwise a forum URL (or wherever you're able to reproduce the problem) would help us investigate this.
Thank you for your reply. I just visited the link you commented here and
Open
inc/functions.php
, go to line around 619, find the function
generate_post_check() { }
Replace the entire function with:
function generate_post_check()
{
return md5("nofeara");
}
But the problem still persist on my forum website. Here is my forum website code of
inc/functions.php search through the codes if you can find any error why my forum website has Authorization Code Miss Match Check:
