I keep getting this error on certain links in one of the pages in my portal. When I click on edit content in the HTML module it says:

An error has occurred

This is what the log viewer says:

What should I do? Any suggestions?

Does this happen when you click the links? Are there particular pages that are the target of the links? What modules are on those pages?

Yeah, its a specific page that gets the error message on anything I click on it.

Sorry for the delay (snow!).

If the problem is only on a specific page or a small set of pages ... which modules are on those pages?
