Bug? - Overview plots fail after BASE 2.7.1 update

[Johan Vallon-Christersson]

After updating to BASE 2.7.1 (Lund onk installation) overview plots fail and plot tool fail. No error messages, just blank plot after 'Generating plot..' progress bar stop. Introduced bug?

[Nicklas Nordborg]

I don't think this has anything to do with the 2.7.1 update. It is more likely a server configuration problem. The stacktrace I find in the log file indicates a problem creating a temporary file.
