My redirection set from cPanel shows an error
When having problems with such redirection, log in your cPanel, go to the File Manager and navigate to the directory in which you'd like to set the redirection.
Then rename the file .htaccess to htaccess. This will disable any previous redirection / rewrite rules which might be in conflict with your last one.
Finally, add again your redirection and there should be no problems. You can also check this link for relevant information.
