Error: exception thrown during rendering of a template


The following error was presented in a Piwik installation, in the dashboard, after login, in the place for the returning visitors widget:

Error in Piwik: An exception has been thrown during the rendering of a template ("Unable to create the cache directory (/path/to/piwik/tmp/templates_c/2c/f9).") in "@CoreHome/_dataTable.twig" at line 33.

Refreshing the widget resulted in it immediately be working again and the error did not reappear.

Any thoughts?


Has anyone encountered a similar problem?

Hi Peter, it should be OK if the error is gone after a refresh. it could be a small side effect of the upgrade but should not affect beyond that.
