Hello,
Be attentive, don’t post private information out of the Private content area because it will be visible to all the users of the forum. Only content that you place in Private content is visible to the support staff only, so I’ve edited your reply and moved access to the Private area.
1/ Update the theme and Core plugin – https://xstore.helpscoutdocs.com/article/63-theme-update https://xstore.helpscoutdocs.com/article/37-plugins-update
2/ 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 the reason for the problem.
Let us know the results.
Regards
