Theme crash

Got an Auto dealer theme and it crashed.
Fatal error: Wrong vc_map object. Base attribute is required in /home/dembrothersauto/public_html/wp-content/plugins/js_composer/include/helpers/helpers_api.php on line 26

How can I just get money back or a credit? Piece of junk.

Except that this error comes from Visual Composer, not from theme
Better contact theme author support and they will help you

Does your theme include custom visual composer modules, or are you using another plugin that includes custom vc modules? It sounds like they might not be mapped properly. We would suggest contacting the theme (or plugin) author for support.
