Sorry for the late reply, as I forgot that I wrote here and was still searching for a solution about this issue.
The issue is; The external links are opening on an external page which is what I wanted. But at the same time they are opening on the parent frame. So, they are not working properly! I have tried both _blank and _new but the same problem.
I just want them to open on a different page and the parent frame staying on the current page.
Please try the links from the line on the following page, and help me with a solution.
