When navigating to an object's tab (Accounts, Leads, Contacts, etc.) and clicking on the built-in "Show 10 Items" or "Show 25 items" link you get the following error:
"Unable to Access Page The value of the "preference.value" parameter contains a character that is not allowed or the value exceeds the maximum allowed length. Remove the character from the parameter value or reduce the value length and resubmit. If the error still persists, report it to our Customer Support team. Provide the URL of the page you were requesting as well as any other related information."
The URL is being appended with ";window.top.pd.executeShowMoreButton(window);" when clicking on the link.
Example Full URL: https://na1.salesforce.com/setup/set_preference.jsp?retURL=%2F001%2Fo&preference.value=10;window.top.pd.executeShowMoreButton(window);
