[SOLVED] Strange problem

I've developed a site in a temporary domain, so in it working all very well.
Finish the site I've transfer it in the right domain on the same server (VM) of the temporary domain.
In the right domain strangely 2 pages that have a Zh modules don't work and I've a 500 error. The pages working if I turn off the modules.
The pagese of temporary domain are:

agriturismovip.it/contatti-dove-siamo.ht...atti-dove-siamo.html

agriturismovip.it/azienda/business-partn...usiness-partner.html

The pages on the right domain are:
amsrl.org/azienda/business-partner2.html...siness-partner2.html

amsrl.org/contatti-dove-siamo.htmlhttp:/...atti-dove-siamo.html

Many thanks in advance for your help
