"There appears to be an issue with this svg file. The svg contains measurements that are in a format other than pixels (such as points, inches, centimeters, percents, etc.) WarLight only supports pixel measurements. Please configure your application to output the svg in pixels, and ensure that percentages aren't used anywhere."

This is the message I get when I try to upload my map, I checked and messures are in pixels, I changed it to another, saved, changed to pixels again, adn saved, then uploaded again and the same message pops up.

Any idea why or what can I do?

What editor are you using? Did you set it up via the instructions at http://wiki.warlight.net/index.php/Creating_the_SVG?

I'm using inkskape, it finally worked, without changing anything, and I could upload some versions, then I had troubles again and I stopped trying, and now it is working again.
I did what I always did and I've had problems.
