We recently added a simple ecommerce option to a WordPress site (www.parkfarm.co.uk) using the great ‘Simple Cart and Buy Now’ plugin.
However I did have to make some tweaks to it – namely to allow the client to add their basic shipping cost and to make the Add to Cart button *just* add to cart and not take the customer to the product page.
It all worked wonderfully – until the client decided to update all the plugins.
Lo and behold my new customisations vanished and customers were buying without a delievery cost. Oops.
Luckily I had a backup of the changes I had done and could restore the plugin to its former glory.
But how to prevent the plugin from telling the admin user to update again?
Luckily I found this post below which did the trick.

(Note it has a second part as well. Make sure you do that if your plugin already thinks it needs updating.)
