Fix X-Frame-Options' to 'sameorigin Problem on URL Shortener Script

Hello, i want make advertising on my url shortener website [login to view URL] and the ad company said that the problem is X-Frame Options. THis is what the support said: Straight from the console: "Refused to display [login to view URL] in a frame because it set 'X-Frame-Options' to 'sameorigin'." The above means that the website in question has not been configured to show nothing inside a 3rd party frame. Therefore, if we approve an advertisement, all visitors will just see blank page. If the X-Frame-Options for said website get modified to allow 3rd party framing, you can submit your advertisement for review again. Please note the problem is that ALLOW-FROM is an obsolete directive that no longer works in modern browsers and this means that even if you use it, the reviewer will still see a blank page and will reject the advertisement to protect you from wasting clicks/visits. I hope someone can help me, that my script works on modern browser without this problem.
