I just started using Inkscape today and began making a logo for my robotics team.
The logo consists of a phoenix that has overlaid text reading "Project Phoenix", with various other descriptors around a circular path.
For some reason, the "Project Phoenix" text that is overlaid on top of the phoenix bird graphic does not properly show up when viewing the SVG in other programs or attempting to use the SVG in other uploads.
I am using a Mac running OS X El Capitain. When I render the SVG using Gapplin, the "Project Phoenix" text does not appear. However, when I attempt to upload the SVG to the t-shirt designer on The Graphic Edge, the "Project Phoenix" text appears as an orange block with various black blocks that form around it.
When I save the SVG to EPS and PDF formats from Inkscape, the rendered graphic appears to look as it should.
If anyone might be able to provide some insight as to why the SVG is not rendering correctly, and does so differently in different situations, I would greatly appreciate it!
Below are some screenshots of how the SVG is supposed to look (once rendered in EPS and PDF file formats) and what happens when rendered in Gapplin and on The Graphic Edge t-shirt designer.
