Cause:
The issue is the same as FA209340, however the fix for PME 8.0 will not work in PME 8.1. Attempting to apply the 8.0 fix will result in further errors in the Windows Appliaction Log:

Resolution:
The hotfix webreach.dll is available to resolve the issue in PME 8.1.
The updated version of webreach.dll is attached along this article which will address this problem in PME 8.1 systems. Please follow the steps below in order to deploy the hotfix.

To deploy:
1. Navigate to [PME root folder]\system\webreach\bin folder and then look for "webreach.dll" file
2. Make a backup copy of existing "webreach.dll" file ** The back up copy of the file cannot simply be renamed.  It must be moved to another folder entirely or IIS will still pick it up and load it.  **
2. Copy the attached updated "webreach.dll" file into \system\webreach\bin folder.
3. Do an iis reset and clear the browser cache.

This should resolve the issue.

NOTE: The issue is the same as FA209340, however the fix for PME 8.0 will not work in PME 8.1.
