Correct, it is, so you should debug it and identify which part it does not like.
My guess is that it might be related to user agents.
Try this.
Go to oc-includes/osclass/user-agents.php
Replace old list:
$user_agents = array(
'MSIE ([0-9].*)$',
'^Mozilla/[0-9].([^c][^o][^m].)$',
'^Mozilla/5.*Gecko',
'^Mozilla/5.(PLAYSTATION.)',
'Safari',
'Omni',
'iCab',
'Opera',
'Konqueror',
'AOL',
'MSN',
'WebTV',
'BlackBerry.*'
);
With new list:
$user_agents = array(
'MSIE ([0-9].*)$',
'^Mozilla/[0-9].([^c][^o][^m].)$',
'^Mozilla/5.*Gecko',
'^Mozilla/5.(PLAYSTATION.)',
'Safari',
'Omni',
'iCab',
'Opera',
'Konqueror',
'AOL',
'MSN',
'WebTV',
'BlackBerry.*',
'Trident/.*rv:11\.0',
'Chrome',
'CriOS',
'FxiOS',
'Edge',
'Edg/',
'OPR',
'Firefox',
'SamsungBrowser',
'UCBrowser'
);
