Custom Actions: Work OK in stand alone report - Fail when embedded in HTML page

Custom Actions: Work OK in stand alone report - Fail when embedded in HTML page

I have never had this problem (see details below) before and have been running the apps in question for years. Has something changed on the Zoho end? Do I need to add new parameters?

Within an HTML view I have a report named "SessionsNotYetBilledADMIN". The code for that part of the page is below.

<td><div elname="zc-component" viewlinkname="SessionsNotYetBilledADMIN" params="zc_Header=true"><br />
&nbsp;</div></td>

If I load the report outside of the HTML page, the Custom Actions work fine.  Within the HTML page Custom Actions fail.

In Microsoft IE nothing happens when I click the Custom Actions button, but I do get this error message:

In Chrome, no error message, just no action.
