Error module channels

Channels module: an error occurred while watching a channel after the update. The guest sees a blank page when viewing the channel.

If login to site, then channel viewing is normal.

In the server log, when a guest watches a channel:

AH01071: Got error 'PHP message: PHP Fatal error: Uncaught Error: Call to a member function checkAllowedProfileView() on boolean in /var/www/vhosts/site.name/httpdocs/modules/boonex/timeline/classes/BxTimelineModule.php:2192\nStack trace:\n#0 /var/www/vhosts/site.name/httpdocs/modules/boonex/timeline/classes/BxTimelineModule.php(2470): BxTimelineModule->isAllowedView(Array, false)\n#1 /var/www/vhosts/site.name/httpdocs/modules/base/general/classes/BxBaseModGeneralModule.php(984): BxTimelineModule->checkAllowedView(Array)\n#2 /var/www/vhosts/site.name/httpdocs/modules/boonex/timeline/classes/BxTimelineModule.php(539): BxBaseModGeneralModule->serviceGetTimelinePost(Array, Array)\n#3 /var/www/vhosts/site.name/httpdocs/inc/classes/BxDolRequest.php(97): BxTimelineModule->serviceGetTimelinePost(Array)\n#4 /var/www/vhosts/site.name/httpdocs/inc/classes/BxDolRequest.php(57): BxDolRequest::_perform(Array, 'BxTimelineModul...', 'serviceGetTimel...', Array, false)\n#5 /var/www/vhosts/site.name/httpdocs/inc/classes/BxDolS...\n', referer: https://site.name/page/channels-home

Or: 

[php7:error] [pid 10533] [client 0.0.0.0:51219] PHP Fatal error:  Uncaught Error: Call to a member function checkAllowedProfileView()$

And I don't see the "Search Results By Hashtag"block. It is not in the list of available blocks to add to the page.

Please check, the error for everyone or just my site.
