YInformer tries to keep a running track of internal errors and will alert you if something goes wrong.  These are in reference to the numbers in red in the image above:

1. If you notice red triangles with ! in them (figure 1), that means there was something that happened to cause an internal issue.  You can then click on the View Error Reports button to see what happened.  A new form will appear to explain what happened and give a specific error number.  See below...

The date/time box will tell you when it happened.  The next box to the right will give a list of errors, you can click a specific item in this list to see the details and resolution offered.  This error was a forced incorrect username to get a screenshot of the error reports.

Extra:

You can choose to save any selected error as well for your own records or if we request that you do so you can send them to us.
