I'm using 1ShoppingCart for payments. I have 700 recurring orders per month going through amember. All of a sudden (out of the blue it seems) on May 4th, 2016 - All recurring payments stopped posting to amember. Interestingly enough, all new orders in the recurring series are posting just fine (if a new order is placed) it creates accounts and everything normally, but as of yesterday, I've had about 20 payments expire seemingly overnight (when the person made the payment in 1shoppingcart - and has many multiple previous payments that have posted successfully with the same product same sytem same settings). All of a sudden the reccuring orders never seemed to reach amember and had to be manually entered to give access. I am using version 4.7.2 of amember still currently - not sure if this was set to cause issues on May 4th, 2016 with 1shoppingcart. but I wanted to make a thread. I will be updating the plugin tommorrow.
