Yes, yesterday I saw this page and tried to follow all the tips mentioned but nothing changed, the error is generated if I create a page (account or even a different name) and enter the shortcode [ultimatemember_account], any other shortcode accepts it and does not generate the error.
Thanks Veronica for the link, I spent half a day trying to solve the problem without success, I even uninstalled the plugin and reinstalled but nothing changes, I always get redirected to the account page, I don’t know what to do… and this page is not editable, I even deleted it and added it as new but I always get the error “Update failed. The response is not a valid JSON response” if I enter the shortcode [ultimatemember_account]
