How Can I contact another user?

I recently bought a PHP script and when I update it I still have the same issue I had when I bought it. Login + register pages always forward to 404 pages. I told the seller about this but they always say, that there’s no issue. Now I saw other users mentioning the same and they have fixed it by adding a code snippet to the htaccess file. I would like to contact this user to have the same fix as the author says there’s no issue and now my support period has expired.

How can I contact this user (no seller)?

Hi, You have only one option to contact them. you can go to their profile page and can use the right side contact form. Thanks
