elgg 1.7.1 errors

I haved installed elgg 1.7 in a shared hosting to make a theme and every thing was fine until I uploaded elgg 1.7.1 just to see if my theme was going to work on it, and what I found...It gaves errors on every image, even without I enabled my plugin. Elgg top bar, footer, icons all of them are curropted.

Does any one nous how to fix this issue?
