Product, Media error

[jeffld2]

I just installed Abantecart through softaculous. I went in to add a product to see how it looked. Under product in the media tab i see error not acceptable in all the media blocks.

I checked the error log at my server and it shows: file does not exist  404.shtml   406.shtml and robots.txt

[abantecart]

I am not understanding the error. Can you post screenshot?

File 404.shtml and 406.shtml are not abantecart files.

What type of server or hosting do you have?
