nanoDLP crashed

I tried to upload a svg. file and afterwards nanoDLP crashed.
Now I do not get working nanoDLP anymore,
even if I reboot Raspberry, the website is unreachable.
What can I do to get nanoDLP working ?

Here is a part of /var/log/printer.log:

Re: nanoDLP crashed

It currently does not support palleted color space. I will add it with next beta release.

Remove your mask file manually. Connect through putty type following command.

sudo rm /home/pi/printer/public/plates/mask.png

Meanwhile you can convert your mask file to RGBA color space and use it.

Re: nanoDLP crashed

Now nanoDLP is working again.
I  converted the Projektor Mask from grayscale into 24 bit color and it works
thank you
