Fatal Error: Cannot redeclare …

Can you help me? This occured right after activating the plugin. No backend access possible. Seems like the “onfleek”-theme is conflicting.

Fatal error: Cannot redeclare cmb2_metabox_form() (previously declared in /homepages/3/d706270554/htdocs/clickandbuilds/pagename123456/wp-content/themes/onfleek/inc/df-core/plugins/cmb2/includes/helper-functions.php:302) in /homepages/3/d706270554/htdocs/clickandbuilds/pagename123456/wp-content/plugins/timeline-express/lib/admin/CMB2/includes/helper-functions.php on line 356
