A certificate error in Internet Explorer occurs when a website's security certificate is invalid. When Internet Explorer detects an invalid security certificate, the browser will produce an error message.

Open the "Start" menu. Click the “Run” icon. Type "regedit" into the “Run” text box, and click “OK.” The Registry Editor will appear.

Open these folders in the left side of the editor pane window, in the following order:

"HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Internet Explorer/Main/FeatureControl"

Select “New" and click the "Key" option.

Press "Enter."

Choose "Modify" in the edit menu, and, in the modification area, enter the number “1.” Click "OK."
