Looks like firefox, what client ? All clients ? Does it work in IE ?
Have you (or anyone at your site) done anything [new] recently with respect to FormAPI code associated with the DCTs?I suggest you [temporarily] disable references to any FormAPI code in your DCT and see if the DCRs load okay. If they do - the problem is somewhere within your FormAPI code and you have to debug that.If the DCRs still don't load properly when you have the FormAPI code disabled - then the problem is somewhere else - but I'd be surprised if that's the case (if it is, post again)
What is the "new release" you had yesterday ? Obviously not a TS upgrade.
