I cannot enter the “username” in “To” textbox to send messages. No username list appears. The texts below showing “Searching….”. (attached) I waited for a long time and it just is stuck there with the same displays.
I tried with different usernames, getting the same results.
Could you please kindly help to resolve the issue? Thank you.
This can happen if your website rest api is not working or you have conflict with any other plugins or theme.
Can you deactivate all other plugins and change theme to one of default theme then try?
Or you can give me access to your website if you want me to debug for you.
