Hi Tonygao,
Sorry for the trouble you are having and thank you for reporting this to us. Our dev team is trying to replicate it but have not been able to do so yet.
We would love to get more information on what messages you are actually seeing. I’m not 100% certain without further information on the cause of this issue, it could be a third party plugin interfering with our code or a theme.
Can you please open a support ticket on our website so that we can identify the issues, I don’t think it’s a good idea to list your information on a public forum, we have some questions to follow up.
If you can submit a ticket on our website here: https://www.echoknowledgebase.com/technical-support/
Please fill out the form as best as you can so that we can further diagnose your issue.
Thank you!
Dave.
