Error after update

got the following error after updating. Grateful for any assistance.


/piwik/core/Plugin/Controller.php(688): Notice - Undefined index: enable_measure_piwik_usage_in_idsite - Piwik 2.14.0

Hi there,

please reupload all your Piwik files as it looks some files were not uploaded properly

thanks Matt. I’ll have a crack and let you know what happens

for the record, this occurred after an automatic update.

Same problem here. After an auto update, I get a core error and 500 server error.

Same here: auto upgrade resulted in a blank screen and now i cannot login anymore. It keeps sending me back to the login screen :confused:

Hi guys
What is the error in your server error log file?

Error log below…

Today, downloaded the new version and uploaded all files to the PIWIK directory on my server. After this, nothing changed. Same error page.

Here is the FAQ that should help you: After the update, I get sql errors, I would like to try the update again. How do I force Piwik to re-upgrade the database from a past version? - Analytics Platform - Matomo

it looks like your problem is that some DB upgrades were not done as expected, at least as far back as ‘2.0.3’ release.
