[FX.php List] Page expired problem

[Jonathan Schwartz]

Troy,

I'm sorry for diverting the original question, but can you recommend 
Blackbelt for the CDMl to php translation?  I have a new client using 
FMP 5.5 Unlimited with CDML pages and is battling crashing problems 
after a recent hardware failure.  One option could be to dump the web 
Connector part of Unlimited and let a real web server do the job.

Thanks

jonathan
