Excessive logging

I keep getting logging entries like:

23/3/13 3:13:13.155 PM Textastic[158]: setFileURL: file://localhost/Users/rcarmo... - isMainThread:1

23/3/13 3:13:13.161 PM Textastic[158]: readFromURL:file://localhost/Users/rcarmo...n ofType:public.json error: - isMainThread: 1

23/3/13 3:13:13.194 PM Textastic[158]: Menlo-Regular

Can these be switched off, please?
