what version do you have?

   118     OW::getCacheManager()->clean(array(PostDao::CACHE_TAG_POST_COUNT));

        $userId = $params['userId'];

        $count = (int) $this->service->countUserPost($userId);

and in the links classes event handler i show it on 245

// blogs code    public function onCollectEnabledAdsPages( BASE_CLASS_EventCollector $event )    {        $event->add('blogs');    }

//links code 

    public function onCollectEnabledAdsPages( BASE_CLASS_EventCollector $event )    {        $event->add('links');    }

Maksim lets wait for a team member to look at this, im not sure whats going on here, sorry i wish i was more help but ill keep digging for you.  

What is your software version and what is the plugin version you have?

Maksim, switch to the default theme and see if the issue persists if not, then it is a 3rd part theme issue, contact theme developer to resolve it.
