I upgraded from 1.235 to 1.238 and suddenly all my matrix builds stopped
loading. The log contained the following style of message for each matrix job.

I backed down to 1.237 and the problem went away. Did try disabling all plugins
and a few restarts on 1.238 without any luck. Also tried reconfiguring security
to logged on users can do anything. Let me know if job configs would be helpful.

Thanks,
