[RESOLVED] ERROR: Feed could not be created, undefined


Haven’t added any new feeds recently, but now I am having trouble when creating new feed from input, or to change already existing feed.

I have upgrades to ubuntu 16lts and php7. everything else seems to be working ok.

Any thoughts where to look? All the paths and permissions are ok and verified.


 // Engines working folder. Default is /var/lib/phpfiwa,phpfina,phptimeseries
    // On windows or shared hosting you will likely need to specify a different data directory--
    // Make sure that emoncms has write permission's to the datadirectory folders
        'datadir' => '/var/lib/phpfiwa/'
        'datadir' => '/var/lib/phpfina/'
        'datadir' => '/var/lib/phptimeseries/'

I am grateful for any info, what helps me on…


Morning is always smarter than evenings.

found my solution from here: https://github.com/emoncms/emoncms/issues/561

Problem was caused by MySQL having a strict mode set which won’t allow INSERT or UPDATE commands with empty fields where the schema doesn’t have a default value set.

and after adding :


to /etc/mysql/my.cnf file, and restarted sql service, everything worked and I was able to add feeds again.

Thank You
