Page Builder – Fatal error turned into Warning then Catchable fatal error

Hi

I had a working WP site and today I turned it into a Multisite.
I created a second site and I could update contents on the first site and create contents on the second site without any problem.
I had not installed Page Builder or any other page building plugins.

Then I installed your Page Builder and Widget Bundle.
When I began creating new contents, after I clicked the “Update” button the screen displayed this message:

Fatal error: Call to undefined function map_deep() in /home/ABC/DEF/wp-content/plugins/siteorigin-panels/inc/admin.php on line 183

I clicked back in the browser and deactivated all other plugins except Page Builder and Widget Bundle.
I tried to update my page but saw the same issue.
I clicked back in the browser and then my page displayed this:

Warning: get_class() expects parameter 1 to be object, boolean given in /home/ABC/DEF/wp-content/plugins/siteorigin-panels/inc/widget-shortcode.php on line 103
Warning: get_class() expects parameter 1 to be object, boolean given in /home/ABC/DEF/wp-content/plugins/siteorigin-panels/inc/widget-shortcode.php on line 88

I checked the version of WP and it was 4.1.18 so I upgraded it to 4.7.4
After the upgrade was complete, any link I clicked on displayed this message:

Catchable fatal error: Argument 1 passed to Genesis_Admin_CPT_Archive_Settings::__construct() must be an instance of stdClass, instance of WP_Post_Type given, called in /home/ABC/DEF/wp-content/themes/genesis/lib/admin/menu.php on line 122 and defined in /home/ABC/DEF/wp-content/themes/genesis/lib/admin/cpt-archive-settings.php on line 38

So I logged out and when I logged back in I saw the last error message on the screen.
And since then I cannot log back into the admin site.

I don’t know where to begin fixing this issue.
Any assistance is appreciated.
