Error popup when lingqing words

I often get error popups when i lingq a new word or want to change the status of a word. Also i like to remove all the blue words by sliding through the lesson before i actualy start the lesson, this also often leads to an error popup. Sometimes i have to refresh the page.

Hi Patrick,
Can you please take a screenshot next time when you get that error message and sent it to support(at)lingq,com? Thanks!

This is what the error popup said last time. SyntaxError: Unexpected token < in JSON at position 0 Please check your Internet connection and visit our Twitter feed for system status updates.
