To quickly resolve this problem, please select the browser you are using and follow the checklist to make sure that cookies are being properly stored.

Checklist of Browser-Related Causes

  • Not storing cookies properly
    • Open Internet Explorer.
    • Select the Gear icon. Go to "Internet Options".
    • Internet Explorer's options menu
    • Go to "Privacy". Make sure the current setting is anything BUT "Block All Cookies".
    • Internet Explorer's options menu, selected at Privacy
    • If your settings are set to "Custom", then select "Advanced".
    • Under Advanced, make sure that "First-party cookies" are always accepted.
    • Internet Explorer's privacy settings
  • Clearing cookies when exiting the browser
    • Open Internet Explorer.
    • Select the Gear icon. Go to "Internet Options".
    • Internet Explorer's options menu
    • Under the "General" settings, find "Delete browsing history on exit" under "Browsing History". If this box is checked, then select "Delete..."
    • Internet Explorer's options menu, selected at Privacy
    • Under "Delete...", make sure that "Cookies" are not checked. Select Cancel.
    • Internet Explorer's privacy settings
  • InPrivate Browsing
    • Using Internet Explorer's InPrivate browsing option will prevent any visited website from storing cookies.
    • If you are unsure whether or not you are using InPrivate browsing, simply look for the InPrivate browsing icon, by the address bar.
  • Beginning new sessions
    • Unlike opening a "New Window", starting a "New Session" will separate web browsing data between the appropriate sessions. New sessions will, therefore, cause more frequent popups from us.
    • The easiest solutions is to open a "New Window" rather than a "New Session".

Other Causes

  • Using multiple browsers
    • If you use multiple browsers, please go through the checklist for other browsers to ensure that cookies are being stored properly.
  • Using a Proxy or VPN
    • The additional server layer from the proxy or VPN may be filtering or modifying the transmission of cookies to your browser. If able, please place the LII on white-lists. The cookies may also end up being flagged as third-party cookies.
