No Data Displayed on Web UI

JGPorteous commented 5 years ago

Good day,

I've setup vnstat-dashboard and I'm not getting any data on the WEB UI.

vnstat is collecting data, vnstat version 1.15 I'm not using Docker, installed to apache2 /var/www/html/vnstat

Errors found in /var/log/apache2/errors.log :

The current version of Master branch is only compatible with vnstat >= 2.0 I think (see #25)

Use a commit befor the merge of that PR and it should work (should be dc2a299a76382c50cbc92fb2e2ac150c8e0b2b3c)

Thank you so much, upgraded vnstat to 2.2 and it's working.
