problem is presented. I use Chrome 11. In firefox, for example, there is no such a message (actually it is shown for a second in a blank page, then redirects)

Don't know what to tell you, I installed all 3 modules on your site successfully for you. Likely something wrong with your install packages. If on MAC then the archives were likely unpacked and repacked with _MACOSX folders which will mess up installs. Aside from that no idea why it's not working for you. At any rate they're installed now.

For future reference anytime you receive a blank page you should immediately enable Joomla debug mode and set error reporting to maximum in Joomla global/site configuration then re-test. This is the only way for errors to display from a blank page scenario or log to your server error log. This step is covered in our FAQ below.

I search from BACK!!-end in admin panel in CB module - User Management
Field "Резюме"-"has file"-> as a result no filter apllied. the whole list is shown

For future reference please keep in mind this is User Management and not a Userlist, completely different things.

Was able to confirm your issue and have created a bug ticket to further address for next release.

That is a known issue with checkbox fields. We've a bug ticket in place for CB to address with next release. Sorry for the inconvenience. Re-navigating to User Management should clear the filter.
