I have try to upgrade from version 1.33 and upgrade failed with message:

Package: Salesforce Agile Accelerator (04to0000000O6AC)

Problem:

1.  This app can't be upgraded.

Salesforce has blocked this package upgrade because the new package version removes some Apex code that one or more Visualforce pages or global Visualforce components need in order to function. Please contact your partner with this error information.

Provide these component names to your partner.

Visualforce Pages: ADM_WorkBugRichGlobalAction, ADM_WorkStoryRichGlobalAction.

Help, please.
