turning off minification in hummingbird

Hi, i have just migrated one site (sportellomeridiana.it) to a new host. This might be the first problem in itself, but the point is that there are some errors happening.

The biggest one right now is the fact that a search form that i have created with a third party plugin (ajax search pro) it looks like it does not respond to style changes made in the backed. then i discovered that if i select the option “see this page unminified” from hummingbird menù on top of the page, it shows correctly.

So i want to turn off minification, but i can’t understand how to turn it off for pages.

Thanks

Matteo

ps: once i solve this, i have unfortunately more problems related to the migration (i think) and i’ll post them here. thanks a lot
