When I tried to access my website I got this message: Call to undefined function vc_add_shortcode_param() in /home/biurokpl/domains/firelens.pl/public_html/wp-content/themes/jkreativ-themes/admin/vc/extend.php on line 27
My hosting provider told me that “jkreativ-plugin is not compatible with latest WordPress”
They have changed some settings now, but I can only see the main page with menu that doesn’t work.
They have left the Jkreativ plugin off.
i don’t believe it is the problem, because I am only one here on this forum who has it now.
Sorry for late reply. Please try to leave Jkreativ plugin deactivated. After that switch Jkreativ theme into another theme such as twentysixteen or etc. After that please go to activate Jkreativ plugin then install again Jkreativ theme. Let us know if you still getting problem in there.
