error messages after transfer with WP plugin Duplicator – reinstall theme?

Hi,
i wanted to Transfer the theme and all of my WP configurations from one Domain to another, so i moved the theme with wordpress plugin Duplicator but the theme doesn’t work properly, i get error messages in the page editor and i could not edit pages:

Warning: Illegal string offset ‘allowed-shortcodes’ in /www/htdocs/xyz/domainname/wp-content/themes/enfold/config-templatebuilder/avia-template-builder/php/shortcode-template.class.php on line 489
Fatal error: Uncaught Error: Cannot use string offset as an array in /www/htdocs/xyz/domainname/wp-content/themes/enfold/config-templatebuilder/avia-template-builder/php/shortcode-template.class.php:489 Stack trace: #0 /www/htdocs/xyz/domainname/wp-content/themes/enfold/config-templatebuilder/avia-template-builder/php/shortcode-template.class.php(443): aviaShortcodeTemplate->create_sortable_editor_element(Array) #1 /www/htdocs/xyz/domainname/wp-content/themes/enfold/config-templatebuilder/avia-template-builder/php/template-builder.class.php(397): aviaShortcodeTemplate->prepare_editor_element() #2 /www/htdocs/xyz/domainname/wp-includes/class-wp-hook.php(286): AviaBuilder->js_template_editor_elements(”) #3 /www/htdocs/xyz/domainname/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters(”, Array) #4 /www/htdocs/xyz/domainname/wp-includes/plugin.php(465): WP_Hook->do_action(Array) #5 /www/htdocs/xyz/domainname/wp-includes/media-t in /www/htdocs/xyz/domainname/wp-content/themes/enfold/config-templatebuilder/avia-template-builder/php/shortcode-template.class.php on line 489

i replaced the correct path in this post with “xyz/domainname”

i purchased the enfold theme through another service provider, therefore i don´t have the ZIP-File to install the theme new, i only have the purchase Code. i already contacted the service provider but still waiting for the answer or the zip-file.

Can i download the theme again from your site or how can i fix the problem?

thank you very much in advance
