Hello,
I’ve created a test file in the directory wp-content/themes/royal/framework/inc/really-simple-captcha/tmp, but the link http://www.zujiss.com/wp-content/themes/royal/framework/inc/really-simple-captcha/tmp/test.php gives 404 error, that the file can’t be found. If you check the directory wp-content/themes/royal/framework/inc/really-simple-captcha/tmp you’ll see the file test.php exists.
So the problem is with your server configuration.
Please contact your hosting provider again.
The issue isn’t related to the script but to the server.
Thank you for understanding.
Regards,
Eva Kemp.
