I'm experiencing a strange issue when trying to modify items in a list in WSS3.
My user is a site collection administrator and should have full permissions on the list. I can view the items, but when I change any of the properties and click OK, nothing happens. The page posts back but it doesn't save my changes.
I don't get any error messages and there is nothing in the logs.
I thought it was this issue http://blogs.msdn.com/b/rodneyviana/archive/2009/12/17/you-cannot-edit-list-or-document-library-items-on-existing-sharepoint-sites.aspx but Rodney's tool reports that the issue isn't present on my site.
I'm at a total loss as to what's going on, any ideas?
UPDATE: I've carried out some more tests, I can edit the list items programmatically and also in Data Sheet view. The problem seems to just be with the standard edit form.
