[CWB] CQPweb: Error: "Call to undefined function check_user_cookie_token()"

[Krzysztof Nowak]

Dear all,

I have updated my local CQPweb installation to the recent version.
After some initial problems with admin user password, everything seems
to work just great with one exception, though. When trying to access
collocation search page from within concordance list
(redirect.php?redirect=collocations), I keep getting a blank screen
with a PHP error message:
"Fatal error: Call to undefined function check_user_cookie_token() in
/var/www/cqp/lib/environment.inc.php on line 252".
Do you happen to encounter a similar error or is it only my installation?
I will be grateful for any hint.

Best regards
Krzysztof

My system settings:
OS: Kubuntu 13.10, 64-bit
PHP version: 5.5.3-1ubuntu2.1
