Yes, but what do the log files say? I think you will find the solution
there.

Hi Luc,

the question is which Logfile does it mean? the appache Error log?

its nearly the same as the standard exception msg.

If there is a specific pisa logfile I can't find it...

No, you need the Pisa logfile. This is indeed not well documented. Maybe
it is just enough to add one line in your Python code:

import pisa
pisa.showLogging(debug=True)

But you can do trickery because Pisa uses the standard Python 'logging'
module. Here is an excerpt from code that works for me to create a log
file per document:

import logging
import cStringIO
import pisa
html = '<html>...</html>'
filename = 'test.pdf'
h = logging.FileHandler(filename+'.log','w')
pisa.log.addHandler(h)
pdf = pisa.pisaDocument(cStringIO.StringIO(html), result)
pisa.log.removeHandler(h)

hth,
Luc
