If our website shows weird behavior, please clear your browser cache & cookies, then log out and in again. That should hopefully help solving the issue.
If this couldn't fix the issue, please email us the following information at [email protected], and we'll be happy to look into that for you:
What browser/version do you use? (In some cases it can be a browser related issue, so it is always best to test it on another browser to see if the issue is reflected there too.)
What steps did you take until you received the error?
Does it occur with a specific book title, or page on our website?
Thanks for your cooperation. We look forward to hear from you!
