Met verversen (via Internet Explorer) kan ik dan wel vaak (maar niet altijd) weer verder. Dit probleem heb ik nog niet eerder gehad. Enig idee?

With a refresh (via Internet Explorer) I can often (but not always) continue. I've never had this problem before. Any idea?

Fortunately, I am not the only one with this problem

I'm afraid everyone has this problem?

I just got back from a night out and see that there is indeed a problem with one of the servers. We will solve this early tomorrow. Sorry for the inconvenience.

The issues were resolved last night. If anyone sees anything else, please email me.

Could something be wrong? I tried to add an image.

Image by image it works (very slow). But 2 images does not take.

Now I'm okay.

Was I the only one affected?

Yip! So it seems ...
