Wg pulling data from 500px is pulling up a 403 error and not loading photos

Using wg to get background pics just suddenly stopped working. Now using the URL results in an error 403 on the browser.

It seems that wg is getting a different address than what is on the feed as the feed is working.

This was a beta issue now fixed

I'm running 3.25 and have the same issue tried the .26 beta no change is there a .26 final out that has the fix?
