Default Icons not shown

This is an excerpt from another forum

i checked the icons.xml all contain the icon filename. also the icon files
are in the icons folder. i think my problem is not the same as @IlluminiX,
because when i tap the tools or setting tab i don't get any "please wait text"
or anything like this. it get to that tab but i can only see the background
immage, and if i click on the places where the icons should be the programs
open(they are there) but no icons.

Does someone have a solution? TIA
