Thanks for your confirmation. We looked at your site and were able to reproduce the issue. We see the error There has been a critical error on your website
appearing at the footer part of your website.
The issue you’re currently experiencing typically occurs due to a conflict. So, we’d like you to please perform a conflict check. The fastest way to do this is to?deactivate all non-Yoast plugins and switch to a standard theme?like?Twenty Nineteen.?
Test this on your development or staging site, if you have one. If not, we recommend using the?Health Check & Troubleshooting?plugin. This plugin allows you to run a conflict check?without affecting normal visitors to your site.
As we can imagine that you’re unfamiliar with checking for conflicts, we’d like to point you to a step-by-step guide that will walk you through the process:?How to check for plugin conflicts.
If you do not feel comfortable doing this yourself or if this does not solve your issue, our Yoast SEO Premium plugin comes with one year of (technical) support.
