You can find this after the exception message in the minimserver.log file (before restarting MinimServer) or in a minimserver-crash log file. These files are in the MinimServer shared folder of your QNAP NAS.

Thanks for the very prompt response, especially at Christmas. Hope you and yours are keeping well.

--- EDIT - config settings now fixed by installing 30 day license, original issue persists ---

Don't know if this may have any bearing, but I previously had some customisations in the config file, eg album title under an artists were sorted in 'Year' order, also has some custom categories showing (Album/Single, Live/Studio, etc). All of the above has disappeared just the basic default headings are showing (Artist, Album, Genre, Composer etc). Do I need to manually reset all these up in the config file or can they be imported from previous.

All this probably unrelated to problem in hand, here is the error log.

Thanks again Simon.
