we track sign ups as Piwik goals at our website apiOmat. Mostly, this works pretty good, but on some days we miss about 30% of all signups in Piwik.
_paq.push([ 'trackGoal', id ]);
The requests do not even appear in the database. Between the signups there is a time span for about 30min to several hours.
Anybody an idea where I can figure out what is happening?
