Can’t get .gpx to work

could you share a .gpx file you are trying to upload ?

I configured my local WordPress instance to accept gpx files and the upload process was ok.

You can find screenshots of the procedure, and a sample .gpx file, at following url:

Thanks for the files. It does not work either with your sample file.
Maybe it is because I’m doing it on a Mac/Safari (don’t have other browsers installed).

Are you using “drag&drop” or are you using the “old style” choose file interface?
Another user in the past had some general problem with Safari and files upload, could you try using a different browser?

So I got one to upload some gpx files from a PC and that works.
My next problem is then that the files downloaded (right click and save as / download file) from the box entry are saved as .TXT, both on my Mac and on a PC.
Is that something with the mime type?

If just clicked they just open as text in the browser.

the plugin is used only during upload, download actions are not handled by it.

you should check your webserver configuration (mime types list) to see if .gpx files are correctly “understood” by the service.

ok, thanks. I solved it with a local php config file on the webserver.
