   page, having Yoast Seo (9.6) installed.

 * Hi [@scubarob](https://wordpress.org/support/users/scubarob/) — have you updated
   to the latest version of Give and run our Give DB Updates?
 * If so, I’d suggest using the Health Check plugin to troubleshoot that. It will
   allow you to deactivate all plugins and put your site on a default theme ONLY
   for yourself — your live visitors will not see that. We have a write-up on that
   here:
    [https://givewp.com/documentation/resources/troubleshoot-wordpress-websites-health-check/](https://givewp.com/documentation/resources/troubleshoot-wordpress-websites-health-check/)
 * Then you can enable plugins one at a time and test again until you see the problem
   again. Then let me know which plugin caused the conflict and I can take a closer
   look at replicating the issue for you.
 * Thanks!
