I'm having trouble finding where to setup the paypal plugin for the K2 store. I'm reading through the k2 store documentation and it says this plugin is included but when I search for it in my plugins, it is not there.. i upgraded the store to the current version and paypal is still not there. What am I doing wrong?

I installed the quickstart of the toreda template.

Hello Christopher, I can see the Paypal plugin is sold seperately
k2store.org/extensions/payment-gateways.html

The plugin is bundled with the Pro Version.

OK, thank you. For some reason before purchasing this template I thought that a paypal feature was included.

Anyhow, I've purchased the paypal plugin and now my checkout screen does not go past entering the billing address. I'm not sure if this occurred when I updated the K2 store to 3.7.5, but checkout seems to be broken now. It was working initially when I tested but I hadn't gotten to the payment portion because I noticed Paypal wasn't set up.

We are not affiliated with K2Store actually, so we cannot sell their plugin.

The quickstart package comes with overrides for K2 Store v.2.6 if you wish to use the latest version you need to download the new overrides, (Check the download section).

Simply download them and copy them over the existing ones.
If the issue persists and you still notice incompatibilities let me know about it.

I solved my problem by reverting my K2store back to version 3.6 - there seems to be some issue with 3.7.5; like I said before, it hangs up at the billing address entry and does not allow you to continue. Version 3.6 works great though! Thanks for your quick responses.

You 're welcome Christopher.
One last thing though a bug was present in earlier versions of K2 Store 3.7

Make sure your site is working properly with 3.6 and it is not affected.
