Sorry, I had a few days off, but I am back!
Based on the screenshot she sent it looks to me that there are two different problems here.
1) if the table based on html is not rendered means either that the RecordingsBN plugin is not finding information in the bigbluebuttonbn_logs table or that the recordings don't exist in the bigbluebutton server.
The only way to confirm that is by reading the logs in both, the BigBlueButton server to se how the request is arriving (if it is) and in the Moodle web server to see how the request is being built.
Do you have access to the logs in both servers?
2) for the second problem, as suspected it looks like a problem with the language packages. What is your language by default in Moodle and what other languages do you have installed?
