Black Screen after Dungeon Alchemist map Import

Hello everyone, i need some help please 😅 I can import a DA map into my roll20 campaign (map Layer) and can adjust it with the auto function, but when i add the script into the chat my map screen turns black (Message: the script is successfully added). I‘ve tried different map-resolutions, but there is no difference. Is there a tile maximum for the maps? The one i tried has 61 x 45 tiles. Or is there another way to implement maps? it‘s my first time creating with the pro subscription and i don‘t have much experience with scripts. Thanks in advance! 

Make sure you have a grid configured on the page.  There is a bug in that script that causes the size of the image to be incorrectly set to 0x0 if there is no grid configured.  I have a patch for that, but I need to re-apply it. Note: you should probably remove that page and create a new one just to clear out all the zero-size objects that you can't easily select.

It worked with the grid. Thank you very much :)
