Upgraded Drupal 6 4.1.1 installation to 4.1.2 then 4.1.3 with no errors reported.
The Activity processor, which used to work now returns this error message:
Finished execution of Activity processor with result: Failure, Error message: Process Activities failed
Where do I look to find out more?
In another thread, which looks similar the request was to look at the CiviCRM log file... Where is this and what is it called?
Many thanks (in anticipation)
