Any fix for timthumb on wordpress 4.0 multisite ?

Hello, i have a problem with timthumb.
I was using external images on my site and it worked just fine.
Until recently i started hosting all my images locally.
Then the problem started, timthumb says:
“Could not find the internal image you specified.”

example:
IMAGE URL:
http://nicoblog.org/psp-iso/wp-content/uploads/sites/2/NPJH50879_00001.jpg

ERROR:
The following error(s) occured:
Could not find the internal image you specified.

Query String : src=http%3A%2F%2Fnicoblog.org%2Fpsp-iso%2Fwp-content%2Fuploads%2Fsites%2F2%2FNPJH50879_00001.jpg&w=160&h=90&zc=1&q=100
TimThumb version : 2.8.13

———-
Now i’ve been searching and it seems this problem it’s been there forever. Timthumb creator blames wordpress, and of course wordpress don’t care.

I found random fixes from 2009,2011,2012. But they don’t work.
So maybe Ajay can help me with this one?

Thanks in advance.
