Readability, Yoast Tab is not showing

Hi @mehdiomnia

We’re sorry that you are experiencing problems that might be caused by our plugin!
?
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.

Thanks
