Thank you for the additional details.
It sounds like some of the issues were resolved, so that’s great to hear.
What do you see in place of the shortcodes?
Normally, if a shortcode cannot be rendered, it will display an error message (unless if you have hidden errors with custom CSS).
Failing this, it may be a good idea to enable logging and check the debug.log file for any errors.
If you cannot find any error messages, I can login to your site and check. If you want me to, please email admin credentials for your site and I’ll login and check.
with regards
