loading maps problem

I using and testing my problem with dude v2.2,v3.0,v3.3 version.I have two networks map the dude.I like more networks map adding the dude. Open the new map and show this message “LOADING”. I can not add new network element, backround image, only show “LOADING”. I change the backround image none or grid, change the maps name other.

What could be my problem?

Thank you the answer.

Hello,

I have the same problem for all maps i want to create :frowning: :frowning:
To bypass this, i go to an existing map (#1), and i add a sub-map :a new map is created (#2). When it’s done, i remove the link added automatically in map #1.
