Where you have: import mod_python.psp change it to: psp = apache.import_module("mod_python.psp") Access the PSP object then as: psp.PSP and not: mod_python.psp.PSP It will happen where somewhere else within the same document tree there is a PythonHandler specified as mod_python.psp as well as the explicit import of mod_python.psp. Depending on which ones gets triggered first, it will screw up. Graham -- http://mail.python.org/mailman/listinfo/python-list
