I just noticed a problem with the "Invite a Friend" link. It works fine in the Dolphin area, but if you go to your Orca Forum and, then try to click on "Invite a Friend" link in the top header links area you will get a 404 Page Not Found Error.
I can't believe I didn't actually notice this sooner. I guess it's not one of the links I tend to click on very often.
Anyway rather than try to run through a bunch of code and figure out where the potential problem is a quick simple fix is just to add a redirect to your .htaccess file.
Example yoursite.com/.htaccess add the following:
Redirect temp /orca/tellfriend.php http://www.yoursite.com/tellfriend.php
Redirect 301 /orca/tellfriend.php http://www.yoursite.com/tellfriend.php
(obviously replace the yoursite.com part with your actual site name.)
Some say google prefers you to use a permanent 301 redirect, but that's up to you.
This is even present at boonex.us
Click on the "Invite a friend" Link and it works fine.
But if you go to the forums:
And try to do the same thing click on the "Invite a friend" Link you will get a 404 error page not found.
I just checked about 6-8 other Dolphin 6.1x sites and it's present on all of them.
