    I have tried uninstall and install still getting this fatal error.

    Hi @tnchuntic,
    we’re sorry to hear that! There is probably some conflict with another plugin using autoload from composer.
    Can you provide us a list of the other plugins that are active on the affected website?
    Would it be possible for you to deactivate each plugin, one by one, to isolate the one triggering the conflict? I understand it can be a long process and it might affect your website, but it would be very helpful to allow us to reproduce and investigate the bug…
    Let us know!

    @priscillamc Nope, don’t do that please. ?? When folks open duplicate topics and it is found then they are asked not to do that and continue with the original topic.

    @tnchuntic If you do still have this problem then use the right sidebar and mark your topic as “not resolved” and continue here instead.

    Hi @jdembowski

    Thanks for letting us know! This is noted. We’ll definitely recommend re-opening the original topic instead of creating a new topic.

    @tnchuntic are you still encountering this fatal error on your website?

    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.
