This seems to be an error whose time has passed.
I went through the tutorial “Make a Gift Tag from Scratch” because I wanted more practice on Inkscape. I followed the tutorial and when I up-loaded it I received this error on the GFUI.
We can’t process text (yet!). All text has been removed from your design. For now, convert your design’s text elements to paths and they will upload successfully. DISMISS
I clicked on the DISMISS button and the error message went away and when I printed the Gift Tag the text was processed (engraved).
I went through the upload process again because the GF acts just like my computers - it doesn’t do what I want it to do - It only does what I tell it to do. There were some items that were only supposed to be scored but the were cut.
Same error message and same result when I tapped the Print button.
So it looks like the error message is no longer needed…?
