Image editor don't show image preview

Hi guys,

I’m having some trouble with wordpress 3.4.2.

When I try to use the Image Editor to crop or resize some images, the image preview doesn’t show at all. Googled for the problem and tried all the possible sollutions but all fails…

What I did up until now:

– Took off all the spaces in the functions/admin-ajax and etc etc etc
– Reinstaled a brand new wordpress in another directory and replaced all the files within wp-admin and wp-includes
– reinstaled the main instalation from the dashboard option
– instaled a new copy of the blog, where the edit works, and replaced the files

The code from Chrome’s inspector:

<div id="imgedit-crop-30577" class="imgedit-crop-wrap">
	<img id="image-preview-30577" onload="imageEdit.imgLoaded('30577')" src="/wp-admin/admin-ajax.php?action=imgedit-preview&_ajax_nonce=2933c95286&postid=30577&rand=23265">
	</div>

And here’s the code from the second blog I instaled:

<div id="imgedit-crop-30643" class="imgedit-crop-wrap">
	<img id="image-preview-30643" onload="imageEdit.imgLoaded('30643')" src="/v2/wp-admin/admin-ajax.php?action=imgedit-preview&_ajax_nonce=40b20af92d&postid=30643&rand=80245">
	<div style="position: absolute; overflow: hidden; z-index: 2;"><div style="position: absolute; font-size: 0px;" class="imgareaselect-selection"></div><div style="position: absolute; font-size: 0px;" class="imgareaselect-border1"></div><div style="position: absolute; font-size: 0px;" class="imgareaselect-border2"></div><div style="position: absolute; font-size: 0px;" class="imgareaselect-border3"></div><div style="position: absolute; font-size: 0px;" class="imgareaselect-border4"></div><div class="imgareaselect-handle" style="position: absolute; font-size: 0px; z-index: 1; width: 5px; height: 5px;"></div><div class="imgareaselect-handle" style="position: absolute; font-size: 0px; z-index: 1; width: 5px; height: 5px;"></div><div class="imgareaselect-handle" style="position: absolute; font-size: 0px; z-index: 1; width: 5px; height: 5px;"></div><div class="imgareaselect-handle" style="position: absolute; font-size: 0px; z-index: 1; width: 5px; height: 5px;"></div><div class="imgareaselect-handle" style="position: absolute; font-size: 0px; z-index: 1; width: 5px; height: 5px;"></div><div class="imgareaselect-handle" style="position: absolute; font-size: 0px; z-index: 1; width: 5px; height: 5px;"></div><div class="imgareaselect-handle" style="position: absolute; font-size: 0px; z-index: 1; width: 5px; height: 5px;"></div><div class="imgareaselect-handle" style="position: absolute; font-size: 0px; z-index: 1; width: 5px; height: 5px;"></div></div><div style="position: absolute; overflow: hidden; z-index: 0;" class="imgareaselect-outer"></div><div style="position: absolute; overflow: hidden; z-index: 0;" class="imgareaselect-outer"></div><div style="position: absolute; overflow: hidden; z-index: 0;" class="imgareaselect-outer"></div><div style="position: absolute; overflow: hidden; z-index: 0;" class="imgareaselect-outer"></div></div>

Anyone had this problem or knows how to fix it?

I have about 5.000 posts in this installation, I cant loose all that…

Thanks.
