Thank you for your patience up to now!

We would like to inform you that Jot Server has been installed and configured, however, there are some issues with the Messenger module itself.

The module does not fully load through neither the frontend nor the backend of the website.

We were also unable to find any log that could contain information regarding why this might be occurring.

Considering this, we could recommend fully reinstalling the module to check if the issue would be resolved.

You could attempt to configure the Jot Server with the Messenger afterward by using the following URL as the Server URL for messenger:
