@Augiz - It looks like there is an issue with your card. I reset your billing information, so please try again to see if it works. If you still have trouble with this feel free to get in touch with us at support (at) lingq.com.
@ajarosz17 - Sorry to hear you’re having trouble with this. Are you reviewing LingQs from the Lesson page, from the Learn page (Top 25) or from the Vocabulary page? Would you be able to check the error console (Using The Browser Error Console - Garden Gnome) to see if any errors show up when the “Internal server error” appears?
When I click the “Learn” tab (not the drop down), all of the history of the lessons I was working on is gone. I can find them again easily enough, so it is OK. On a spot check, my progress on lessons is still there.
@all - Hmm, this may have just been a temporary glitch. We are looking into this further to see if we can find out what may have caused this. If you notice any other issues be sure to let us know!
