Hi Jim
Yes I have been experiencing this issue too. I have also tried to contact Bookry but as yet I have had no reply. There seems to be an issue with Bookry's readercloud service.
Digging into the package content of a Bookry widget. I discovered that many links in the bootloader.js don't seem to point anywhere.
Such as:
http://readercloud.com/account/Pasting the URL in a browser: ">http://readercloud.com/account/
Reveals this page does not seem to exist.
Following any https:// links return a 'Your Connection is not Private Error' and the message:
This server could not prove that it is readercloud.com; its security certificate expired 127 days ago. This may be caused by a misconfiguration or an attacker intercepting your connection. Your computer's clock is currently set to Monday, November 5, 2018. Does that look right? If not, you should correct your system's clock and then refresh this page.
Visiting readercloud.com shows what appears to be a simple static website. With no login/signup options. Also there is no secure connection.
I have also noticed Bookry's social media hasn't been updated for a while!
I am hoping this is a temporary issue, but currently I am looking for alternatives to Bookry to use in iBooks I am currently creating for a client.
