[uMap] Why am I not able to edit my umap anymore?

[Vroni Retzer]

Hi umap-people!

A few weeks ago I found umap as a great tool to make personal maps. 
Since I have started to make a map for planning a travelling route. 
However, for about the last 10 days I cannot edit this map any longer - 
previously it worked fine. I have no idea, why it doesn't work any 
longer. I have tried to access the map with different OS (MS10, Linux) 
and browsers (opera, firefox, chromium), but it worked in none of those.

Any ideas?

Thanks in advance for your help.
