AmmoReady made an update to their platform last night and all AmmoReady users must Sync their categories again.   To do this follow these three easy steps:

Step 1: Click Store Config in the left menu.

Step 2: In the Jump To Box choose ECommerce.

Step 3: In the ECommerce Sync Section check the first checkbox (we recommend unchecking the other boxes) and then click the Sync button.  

You should be all set.  Please contact support if you have any questions or problems.
