I've seen several old posts for this problem but none that apply to newer editions:
Unknown window data - the submitted data is probably too old and thereby pushed out of the list of active windows. This may be because you use the browser's "back"-functionality which cannot be used with this system.
I am running PN 7.6.2 and Pagesetter 6.3.. also running pnCPG 3.5 to run with Coppermine (application linked into postnuke)
Additionally, I am also noticing that in my admin, there are no story types available to me right off the bat- its like something's missing from my install completely- can anyone say what?
Any help appreciated:
