My problem is resolved, so I am posting so other users who might run into the same problem as me can find more assistance.

"I have found out that origin the of the issue is the "curl_version()" PHP function which is used for HTTPS module testing. It causes the server error. I have modified the "include/func.tests.php" file to disable this function execution.

Also I have changed the current HTTPS module from libCURL to Net::SSLeay. This module works fine and does not cause errors.

Actually there is no much difference between the HTTPS modules. So, you can continue using Net::SSLeay instead of libCURL and your store will function fine or you can contact your hosting provider regarding this issue and ask them to resolve the problem with curl_version() function and after that switch back to libCURL (to do this first you need to restore the "include/func/func.tests.php" from the backup which is "include/func/func.tests.bkp.2008_Jul_20.php"). After that go to "Administration menu -> General settings" page and scroll down to the bottom. Here you can change the current HTTPS module using the "Preferred HTTPS module" drop-down. Please remember to click "Save" as soon as you finish the changes."

All I can say is THANKS A BUNCH!
