I run --enable-http-errors option with the import_logs.py script to parse log files.
Piwik displays the 404 pages under both Actions > Pages and Actions > Page titles report.
How can i display Action > Pages report to exclude 404 page views ?
remove the parameter --enable-http-errors when you import the logs.
If you want to hide the data from the UI for already imported data, maybe create a segment to exclude all Page URLs containing 404 ? http://piwik.org/docs/segmentation/
If you found a solution for that it’s a good news, so this forum shows me that if any queries with you just post it, you will get a proper solution on it…
