[enable zip lib] white screen on update to latest versions

Hi!

I have error after upgrade flexicontent to latest versions.

The last worked version (used now)
com_flexicontent_v2.1.0_r1763_J25_J31.zip

All update versions of component result in a white page in an administrative panel at an address to the menu of flexicontent item. Also a white page appears on a web-site in menu items, where a component is used.
I succeeded to find out an error after including of diagnostics
Strict Standards: Declaration of Fatal error: Class 'ZipArchive' not found in /hsphere/loc ...[real path skiped ]... /components/com_flexicontent/classes/flexicontent.helper.php on line 4802

how is it possible to decide the indicated problem?
I tried all versions with numbers higher 1763 up to 1789. A result is the same.

Joomla 2.5.14 php 5.3 is used.

There are yet of less importance problems, but about them later

Hello,

This means, that your PHP installation doesn't have the Zip library.
(please ask you webhosting to enable loading of Zip support for PHP)
