Environment: SharePoint Server 2010

We have a web application, in which there is only 1 site collection with few subsites in it.

The problem is all the modal dialog forms when opened get error message(refer screen shot). Dialog forms such as check in, approve/reject a page, more options from site actions etc.

There are solutions on the web like placing <WebPartPages:AllowFraming runat="server" />, but that can be used in SP 2013.

Also other Web application in the farm works nicely.

In what direction should I continue investigation? And has anyone come across similar issue.

Alright I managed to solve the problem.

Open IIS > Find your site > HTTP Response

If there is X-Frame-Options:Deny, Then just remove it or set value to "SAMEORIGIN".

Removing X-Frame-Options worked wonders for me.

Note: To know more about X-Frame-Options I recommend reading Combating ClickJacking With X-Frame-Options and Mitigating framesniffing with the X-Frame-Options header.
