Upgraded my 4.1 development installation using the latest Apex_listener to 4.2 - now simply get a blank page when starting a development session. Cannot find any errors in Weblogic log files which might help.
Reviewed the installation log file and found the following message;
-- Upgrading Websheet objects. -------
...There are 7 errors in the log table!
...Select upgrade_error from WWV_FLOW_UPGRADE_PROGRESS to review errors.
Cannot find this table. Not sure if it is the issue. Can anyone help please?
