Ok, let's see then. We can be sure now that the problem is localized to the RecordingsBN plugin, although the feed is provided by BigBluebuttonBN, this is why I was asking you to make sure both plugins were updated.
But it's correct. mod_recordingsbn version 1.2.1 (or 1.2.0) works with mod_bigbluebuttonbn version 2.0.3 (or 2.0.4). That being said. It may be a problem with the YUI library, the YUI datatable, the js that comes with the plugin, the js feed produced by bigbluebuttonbn by itself, or it could even be a clash with another plugin library. So let's narrow it down.
Since I haven't been able to reproduce it on my own I am going to ask you to do two things:
1. Since version 2.0.x there are a couple of options you can configure in RecordingsBN. One of them is to enable/disable the use of the YUI datatable to present the recordings. The use of this YUI datatable comes enabled by default. Please configure the RecordingsBN plugin for using only html by checking the box 'UI as html is enabled by default.'
Let me know if this solves the problem.
2. Now, regardless of your result with the action number one, can you please:
a) make sure the HTML option is uncheked in the configuration,
b) enable the development console in chrome (by pressing F12) https://developers.google.com/web/tools/chrome-devtools/debug/console/console-ui?hl=en
c) go to the RecordingsBN page in your course again and see if there are errors in the console.
If there are errors, please take an screen shot and paste it in here.
I'll be waiting for your response.
