Hey Joseph,
Thanks for giving us the FTP credentials. I logged in and the folder that I can access is just the themes folder so I investigated the Pro theme. I found that thereās a woocommerce.zip in the parent Pro themeās folder which should not be the case.

May we know if you have made direct modifications to the theme? If so, please delete the parent theme and download a fresh copy from your Apex Dashboard and install it.
To back up my suspicion, I went to your staging site and switched to X and the Tabs worked.

I uninstalled Pro in your staging site but when I reinstalled a fresh copy, I got this error.

Please upload a fresh copy of Pro in your staging site to continue the test. Contact your web host to fix the expiration error if it persists.
Also note that this is not a bug because X and Pro works in all my test sites and Ruenel also said he canāt replicate this issue. The outdated template could not cause this moreover that itās only a minor area. Itās also going to be updated in one of the succeeding updates. You can check that out in our Changelog.
Thanks.
