1. Use the shortcut key combination Ctrl+Shift+N to open an Incognito or Safe Mode Window. An incognito window is considered to be running Chrome in "Safe mode."
2. Close all other previously opened Chrome windows that are not Incognito.
3. In the this new Incognito window, go to https://www.constantcontact.com.
   Note: If you have enabled any extensions to work in Incognito Mode, you will have to disable them. (Click the Chrome menu  on the browser toolbar. Select More tools > Extensions. On the Extensions page, check to ensure that the slider next to each extension is set to disabled rather than enabled.)

For Safari, you first need to go into Private Browsing to see if that resolves the issue:

1. Click on the File menu, then choose New Private Window.
2. You are now Private Browsing and can tell by the "Private Browsing Enabled" banner displayed below the address bar.​​​​​
3. Go to https://www.constantcontact.com. If the site loads properly, it means you'll need to disable extensions in regular browsing mode.

To view and turn off extensions:

1. Click on the Safari menu, then choose Preferences.
2. Click Extensions.
3. For each extension listed, uncheck the checkbox.
