Within the Goals tab, one can select Campaigns to follow conversions. Unfortunately, there seems to be a bug splitting some compaigns into a upper and lower case version of both the campaign and the keyword string.
This is the URL hash part: [size=small]module=Goals&action=goalReport&idSite=1&period=range&date=previous7&idGoal=3[/size]; I have attached a picture of one example but it really happens in a much wider spread.
The lower case version gets the visits and the upper case the conversions, leading to a false report of 0% rates everywhere.
I am 100% certain that the incoming links only use the version containing upper case letters!
Is this a known bug? It looks like a side effect of Make campaign name and campaign keyword lowercase when tracking · Issue #4260 · matomo-org/matomo · GitHub. How can I help the community to prevent this? I am willing to upload a database dump.
I’m running Piwik version 2.1-RC1 (possibly updated while the campaign was active).
