I have had uddeIM working successsfully over a long period of time (with a low volume of traffic), I am not sure when this issue started or why.
I am able to log into Joomla and access the uddeIM compose message page. The moment that I access the userlist and select a user the userbox background turns red and while it appears that I am able to send a message successfully the recipient does not receive the message (with and without attachments), I have tested this internally from one in-house user to another without sucess.
There is nothing in the Joomla error logs to indicate issues and I am hoping someone can help me resolve this issue.
Joomla 3.9.11
PHP 7.2.9
5.5.5-10.2.12-MariaDB
Apache 2.4.34
MS 2008R2
