What happens?: So, I've been telling this for a long time but no one knows the problem (on miraheze discord server)
There is a problem with the SVG file (Either my original/uploaded or the svg file from wikimedia)
There is no link that can link it to the SVG Thumbnail or the PNG Version of the SVG file
I don't know what caused this to happen, before that nothing happened

Examples of files that are experiencing problems or the link below cannot go to the PNG version of the SVG file :

Wikimedia file : https://tampvan.miraheze.org/wiki/Berkas:Flag_of_Alaska.svg

My original file : https://tampvan.miraheze.org/wiki/Berkas:Bogenglandia_Flag.svg

The link I mean is below the SVG file:
