Hello,
I have the same problem with hanging up of the chat with "loading....".
First I searched in this thread for a solution to solve this. But all I found wasn't working well for my prob.
What is a little bit strange is, that during the iniciation of the chat I have an javascript error, that a refresh of the chat isn't possible:
chatbox_refresh is not defined
[Break on this error] chatbox_refresh('forced');
He trys always to load this function from the old mgc_cb_evo.js from my previous version 1.0. But in the new version 2.3.2 this javascript file doesn't exist!?
I tried everything. Updating, then uninstallation and new installation. Then also to reinstall the old version and uninstal it otherwise, to clean the tables from the old version, and then I reinstaled the new version, but nothing. The error is the same.

As new version, I installed 2.3.2.
Do you have a solution for my problem?
Thanks in advance.
P.S.: During the Update, Change to the new version I also have deleted the old files of version 1.0. Even the mgc_cb_evo_js!
I solved it by myself!! It was an error of an missing security token in my Forumdisplay! After testing other functions of my forum, I had to solve this problem. After that I tested another Instal of the MGC Chatbox, and it works fine now!!
For the security token problem you will find solutions here:
