[arminmacx]

Hi

I try to download from mangafox, mangahere and manga reader but al failed with this error :
"
Traceback (most recent call last):
File "manga.py", line 268, in
main()
File "manga.py", line 257, in main
threadPool.append(SiteParserThread(options, None, None))
File "/Users/armin/Desktop/src/parsers/thread.py", line 37, in init
self.siteParser.parseSite()
File "/Users/armin/Desktop/src/parsers/mangafox.py", line 45, in parseSite
source, redirectURL = getSourceCode(url, self.proxy, True)
File "/Users/armin/Desktop/src/util.py", line 88, in getSourceCode
return ret, f.geturl()
UnboundLocalError: local variable 'f' referenced before assignment "

i try every things i know to fix it but out of luck.
I can download from mangapanda without a problem but from these site nope.
