Error messages in Clan page

Hello.
Yesterday I’ve bought BlueFure theme for my clan page.
I’ve installed it and if works mostly, but have problem with Clan page. It shows error messages and other members can’t join the clan.

For me the error is:
Warning: Illegal string offset ‘pending’ in /home/ziggyarm/domains/ziggyarmy.vxm.pl/public_html/wp-content/themes/blackfyre/functions.php on line 2095 Warning: Illegal string offset ‘pending’ in /home/ziggyarm/domains/ziggyarmy.vxm.pl/public_html/wp-content/themes/blackfyre/functions.php on line 2096

For others is almost same error but the line number is 2360.

Please can you help me fix it?
