Error all around piwik dashboard

Hi Team,

I woke up this morning and bunch of errors are all around Piwik platform.

It seems it started after creation on these 2 archive tables for April 2015:

If I delete them everything is fine and the system works… once they are created
issue pops up.

Please help I have tried everything as a solution on this forum nothing worked :frowning:

Here is a screenshot and copy of the errors:

Piwik 2.3.0 is very outdated, try to upgrade to the latest version and see if the problem is still here.
