Whatssap background photo black and white

[alexan215]

Hello from the new kid on the block...

For the life of me I can't figure this out and it is driving me bananas!!!!!

Just a little while a go the picture I have on the background of my chat windows on whatssap messenger turned black and white.

Here is everything I tried to get it back to color:
change the picture to another color picture
reset the wall paper withing whatssap chat settings and then select a totally different color picture
shut down app and re-start
shut down iphone and re-start
reset iphone and re-start
delete whatssap messenger and reinstall, after reinstall select a totally different color picture
set phone to factory settings and re-insert backup

None of these render my chat background picture to be in color. It is in black and white.

I have an iPhone 5 running iOs 7.1

Any help will be greatly appreciated.

Thanks.
