Hi @justbruno,
Thanks for reaching out! Can you please send me a screenshot with those shortcodes added in the page editor? Also, does the ‘general’ category exist and has testimonials in it?
If it does, can you please install this plugin: https://wordpress.org/plugins/health-check/
After you install and activate the above plugin it has a Troubleshooting mode which allows you to have a vanilla WordPress session, where all plugins are disabled, and a default theme is used, but only for your user – your visitors will still see the normal website.
Go to its troubleshoot mode and only activate this plugin and see if the same happens with a default WordPress theme (Twenty Twenty-two, for example) and no other plugins.
Warmly,
Mihaela
