What happened:  Your web browser tried to interpret the web page’s HTML but could not make sense of it. So the best it could do was to issue the “An error occurred” message then list the HTML code for that page.

What to do:  Just log out of Community Weaver, clear the web browser’s cache, close the web browser, then reopen it and try again.
