For some time now, I am getting the following error:
WARNING: piwik/core/ArchiveProcessor.php(456): Notice - Undefined offset: 39 - Piwik 3.0.2 - Please report this message in the Piwik forums: http://forum.piwik.org (please do a search first as it might have been reported already)
DIdn’t find that mentioned anywhere in the forums before, so here we go with my first bug report…
I have different sites where for long periods of time there are no visits tracked at all (like from March 9 to 23), which is highly unlikely, but I don’t know if that has something to do with this error. Overall, since 3.0, piwik seems completely buggy and unreliable, and if it is not for this specific error, I would love to get some advice what I could try to fix this to gain confidence again.
