Hi @bridieamelia
Thanks for reaching out.
Please try the following:
1. Dashboard > Updates. Make sure WordPress, Page Builder and Widgets Bundle are all up to date. If any pending updates, run them.
2. If you ran updates, try again.
3. Still an issue? Temporarily deactivate all non-SiteOrigin plugins. Test. Issue fixed? Slowly reactivate your plugins, one by one, doing a test after each activation to find the conflict.
