Hi there,

to fix this issue you can execute the Mysql QUERY:

INSERT INTO piwik_sequence (name, value) VALUES ('piwik_archive_numeric_2015_01' , 99999)

Similar issues were repoted on the forum more than once.

Couldn't we simply create the sequence when it isn't found but should be
there?

see #6815

reason we didnt so far put a workaround is because it's a one-off issue, only heappen when old users upgrade, and in quite particular edge case...

IIRC there was one on the german forum having the issue after upgrading
from 2.9.1 to 2.10

I am experiencing the same issue - the insert fixed it for January, but now it is back. Will I have to run the insert each month?

Piwik 2.10.0, always upgraded from dashboard (no manual stuff like ftp uploads, mysql schema upgrades etc).

mysql> INSERT INTO piwik_sequence (name, value) VALUES ('piwik_archive_numeric_2015_01' , 99999);
ERROR 1062 (23000): Duplicate entry 'piwik_archive_numeric_2015_01' for key 'PRIMARY'

I'm still getting this issue after upgrading to Piwik 2.11.

Let me know if there's any more information I can provide.

We need to do something about this bug, adding Major tag

@tsteur maybe you have an idea how we could fix this one in a proper way?

New month, new luck. All my APIs requests from WordPress did have the error for the new month.

INSERT INTO piwik_sequence (name, value) VALUES ('piwik_archive_numeric_2015_03' , 99999)

did solve the problem for now, but I did a regular update via Dashboard and nothing in special. Please fix this before the next month. Thanks.

That's strange but I also got this error in the UI tests after upgrading the OmniFixture, eg. http://builds-artifacts.piwik.org/ui-tests.transitions_deterministic_order/10588.8/screenshot-diffs/singlediff.html?processed=../processed-ui-screenshots/EvolutionGraph_annotations_none.png&expected=EvolutionGraph_annotations_none.png&github=EvolutionGraph_annotations_none.png

I'll take a look at this bug...
