Hi @Omar_Ayaz

The classes are being re-generated/changed each time you visit.

Therefore you have to grab something more stable. Also increase page-delay to like 5000 (ms)

Hope it helps.

Thank you. This works now.
Can you please explain the changes or if they are documented somewhere.

Secondly, I now have the problem that all the images are not getting scraped. It does 16 max then quits.
Is there a log i can check why it quits. I has the child page image-links for a lot more pages.

I increased the delay to 10 seconds and page load delay to 10 seconds as well. It seems to work better.
