Hi,

I'd say I'm still relatively new to Silverstripe, have been using it at work for about 1 year and setup over 15 websites with it.

Never had any issues with the backend, but I have had to setup a more complex sitetree for one particular site and recently have had some issues with the refreshing of the sitetree in the left side bar.

Usually, when you create a page it appears in real time in orange as in the screenshot attached (left-sitetree.jpg). However, not anymore.
When you delete a page, it also gets removed in real-time, not anymore.

I have compared the headers with another site that doesnt have this issue and noticed that in both cases a call to:

POST http://mydomain.com/admin/AddPageOptionsForm gets called sucessfully

but that it should be followed by:

POST http://mydomain.com/admin/getitem?ID=xxx&locale=fr_FR&ajax=1, which is not the case.

(see second screenshot "console-post.jpg" for Firebug info taken from fully functional one)

I have googled and searched various classes and JS files but not figured out a solution to my problem.
Hoping someone can give me some advice :)

Also consider that I have setup various user groups and each group can only edit certain pages.
In Page type classes and in CustomSiteConfig I have also set group specific parts.

Not sure if that could be a possible cause, but I don't think so, at least hasnt happend on other sites where I have used similar conditionals.

Thanks !
