This is a good validator. And the file appears to be fine from my checks. Here is what we have in our wiki for reference (also points to GMOD):
The file name ending with a "gff" instead of a "gff3" is what is throwing off the auto-detection (and triggering the default to bed). You can either pick "gff3" as the datatype from the menu at upload (instead of auto-detect), or re-assign the datatype after upload (Click the icon to reach the Edit Attributes form. In the center panel, using tabs to navigate, change the datatype [3rd tab] and save). I loaded it both ways using the URLs directly from the web site. For both a gff3 file and a fasta file for the same genome.
The fasta file can be used to create a "Custom Build" (User menu -> Custom Build). Assign that as the database to the GFF3 file (on the Edit Attributes form [1st tab] and save), then launch Trackster. This may take a bit to process, so save it (upper right corner disk icon), then come back after a while and check if done. More tracks can be added, if mapped to this same genomic reference.
