I followed the instructions for a scraper and it works for 5 elements but not 50 or 100. What’s wrong?

If you're scraping with multiple rows, you must be using our background scraper. We usually recommend setting a custom delay on the background scraping of 3-5 seconds, just so that page has time to load before the scraper tries to do its thing. You could also update your version of Bardeen to the latest version (2.37.2). We have recently released a new version which addresses this issue. You can check your current version of Bardeen in Google Chrome.
