Did you mean that you tried
pwb.py fixing_redirects -ns:0,4 -links:"Wikimedia Czech Republic/en" pwb.py fixing_redirects -ns:0,4 -ref:"Wikimedia Czech Republic/en"
and both failed?
Yes, exactly.
What error message did you get? Sharing a full copy of the error message usually helps.
I'm sorry that I didn't posted it. And since I deleted the logs, I can't retrieve it either :-(
Sorry again.
