I found an issue with adding non-HTTPS sides to the reading list.
For instance the internet side "http://www.vanion.eu/" can't add to the list. I think it depends of the "HTTP". All HTTPS sides are adding to the list correctly.

Can you confirm and fix it? I think then it's 5 stars worth.

Thank you in Advance.

Note2: With the newest V2.4.5 is it 5 Star worthy!
