I am trying to install a plugin in my current production of APEX 5. During the installation of the plugin it produce an error, Error at line 89: PLS-00201: identifier 'APEX_APPL_PAGE_IGS.DOWNLOAD_FILENAME' must be declared. And when i checked the view APEX_APPL_PAGE_IGS is missing. The application is only retrieving data from the oracle database. Can i create back the view. Is there any impact to the application if i create back the view. It seems that the application has been running well without this view until i want to install this plugin. Appreciate you help.
Software/Hardware used: APEX windows 5.0.3.00.03, oracle 11g xe, windows server
