I’m getting the following error to https://halprince.com following the latest update to Cornerstone 10.5 that is preventing the pulldown menu from working.

WordPress version 6.1.1
Active theme: X (10.5) Child Theme (version 1.0.0)
Current plugin: (version ) PHP version 8.0.26

There is a new version of Cornerstone, which I installed yesterday but it broke my site, so I’ve restored it.

Please advise.

Thanks,
Marj

X and Cornerstone needs to be updated together and that’s most likely what this issue is. So in your account download Cornerstone 7 (since your site is already on x10) and upload that in your plugins area and you should be fine. Let us know if you have any questions! Have a great day.

That did the trick! Thanks so much.

You are most welcome, Marj.
