I was working in my Inkscape .svg file tonight and suddenly objects started disappearing in chunks and then quickly the whole file appeared white. Closing out of the file and reopening it did not fix the issue. My other Inkscape .svg files still open correctly, but this file in question continues to appear all white, even though there are still 282 objects of various formats to be found in the document. I can view the html code and it appears full and correct, but I have not been able to successfully open the file in any other .svg editors. Exporting the file as a .eps also was not successful, nor was uninstalling and reinstalling Inkscape or restarting my computer. I currently have multiple versions of the file saved locally, all of which have what appears to be the appropriate code in them, but I have not yet found a way to view any of them. I saw this forum post (https://alpha.inkscape.org/vectors/www.inkscapeforum.com/viewtopicd023.html?t=35636) which appears to be a similar problem to mine, but there has been no solution. And considering I still have what appears to be a full html file I am hoping there is still a way to save this work. I feel like I'm going crazy I have no idea what happened. Any help would be very appreciated.

Hi Emptynull2,

I took a look and it is beyond me.
But what OS do you use and which version of Inkscape?

If you are working with the newest Inkscape on important files, maybe try installing 0.92.5 for now, until 1.0 is more stable.

You have a sheer size problem. That´s the values for the first path in the layer:

I tried to group everything and scale down - but no luck so far. It seem to exceeds the max values of 1000000,000 units. 

When I take to Affifinty Designer and try to scale proportional to a more reasonable size like 1200px width the Height is just 0,000136px - doesn´t make any sense to me.

To get back on track, I'd delete path2808 in the Objects panel. Then (with nothing selected), Edit > Resize Page to Selection (Shift + Ctrl + R). Then, Zoom to fit page in window (5).

Good catch - I wasn´t expecting just one weird object so I didn´t start a search for more.

Oh my gosh, this fixed it! I have no idea how that object was created. Deleting it and resizing made everything visible again. Crazy how much of a headache one misplaced object created! Thank you all so much for your help!! It is super appreciated!

@Aero, how did you find the offending object? There were about 300 objects in the file ( and hundreds of defs to clean).

(Well, it is the second one in the objects panel, lol)

This code at the end of the file caught my attention in Notepad++.
transform="matrix(45318019000,0,0,5101.3789,-7.8767269e14,-21035576)"

Deleting just the transform, do the trick, but deleting the whole object is just easier to explain.
