Hello,
1/ Is our Email Builder enabled on your site? 2/ Please check if you have the same error when a default theme is activated. 3/ Update theme and Core plugin – https://xstore.helpscoutdocs.com/article/63-theme-update https://xstore.helpscoutdocs.com/article/37-plugins-update 4/ Try to disable all the third-party plugins (including cache plugins), that do not come bundled with XStore https://xstore.helpscoutdocs.com/article/36-included-plugins , clear the cache of the browser, and check then. Maybe one of the additional plugins is a reason for the problem.
Regards
