Link Editing Modal - Redirect Problem

[nbcommunication]

Hello,

One of our clients has an issue which I haven't seen before. When they go to edit a link in the body field (CKEditor inline mode), the modal box appears, but is populated with their website homepage.

An example link from the modal's iframe is: /processwire/page/link/?id=1300&modal=1&href=http%3A%2F%2Fwww.charlottejamesedinburgh.com%2F

When I go to this in a new browser window, it redirects to the homepage. It only seems to do this if "http://" is at the start of the link (which is should be). If I remove the http:// in the source - it opens fine. It is the same on all the pages I tested.

They are on a shared hosting platform which we don't control, so I'm assuming this is probably responsible. If tried switching the two htaccess lines - RewriteRule ^(.*)$ index.php?it=$1 [L,QSA] &  RewriteRule ^(.*)$ /index.php?it=$1 [L,QSA] - but this didn't have any effect.

Any ideas what could be causing this redirect? There's nothing in the htaccess file which is different to how we have the large majority of our sites set up on our own hosting platform.

Thanks in advance!

Chris

Hello,

This was caused by a ModSecurity rule on the client's hosting environment - more info here: https://www.trustwave.com/Resources/SpiderLabs-Blog/ModSecurity-Advanced-Topic-of-the-Week--Remote-File-Inclusion-Attack-Detection/

Cheers,
