I have just deployed a web site on my host that makes use of the DataObject_Manager, Image_Gallery and SWFUpload modules with a custom theme and number of custom models. Now, /dev/build built with out any problems and the front-end of the site renders perfectly but when I log in to the admin interface and select a page in the site structure it keeps showing an alert box with this:
<html> <head><title>502 Bad Gateway</title></head> <body bgcolor="white"> <center><h1>502 Bad Gateway</h1></center> <hr><center>nginx</center> </body> </html>
In fact, it seems to give this problem with every AJAX request going out. I have cleared my browser cache, I've also checked if my other SilverStripe sites on the same host are giving the same problem, but all seems well - they are running version 2.3.2 though.
Does anybody perhaps know what could be causing this behavior?
Thanks in advance.
