We’re sorry that you are experiencing problems that might be caused by our plugin! Yoast SEO will only output a single meta description even if you enter the same details in the excerpt and the Yoast metabox snippet editor. If your site’s source code contains two meta descriptions, another plugin or theme feature is adding the second one.
Just to be sure, we would like to rule out any plugin or theme conflicts that may occur. 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.
