After entering admin user & password at this URL: http://www.yxz.com/admin.php the URL changes to: http://www.xyz.com/admin.php?p=login - but there is no page loaded (source code is blank)
however, if I change the URL back to: http://www.xyz.com/admin.php, then the logged in admin page loads OK & is logged in to admin.
If I try to log-out of admin, the URL changes to: http://www.xyz.com/admin.php?p=logout - but there is no page loaded (source code is blank) however, if I change the URL back to: http://www.xyz.com/admin.php, then the admin page (logged out) loads OK.
Similarly, if I include a "Redirect to URL" on a page, for example: http://www.xyz.com/calendar/availability/rates-availability.php and then go to the link, the following URL is loaded into the address bar: http://www.xyz.com/?en_availability,19 - but there is no page loaded (source code blank)
I am using QuickCMS on the same webhost for other websites, but this problem does not occur. The version with this problem is 5.4. Other versions in use on the same webhost are 2.5 & 4.1.
