[MSNoise] Web interface internal server error

Hello, I have just installed and setup MSNoise (and MySQL and MySQL Workbench) on my new Mac. I have successfully done scan_archive but my problem is that when I try to use the web interface to view "Data Availability" I get the following error message: "Internal Server Error - The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application." In the terminal, the message is: "InternalError: (pymysql.err.InternalError) (1412, u'Table definition has changed, please retry transaction') [SQL: u'SELECT count(%(count_2)s) AS count_1 \nFROM data_availability'] [parameters: {u'count_2': '*'}] 2017-09-06 12:36:04 [INFO] 127.0.0.1 - - [06/Sep/2017 12:36:04] "GET /admin/data_availability/ HTTP/1.1" 500 -" Is there something I have done in MySQL Workbench? Any ideas on how I can view Data Availability and Jobs? Everything else appears to be working, I have all my data in the MySQL database.
