Ajax warning when trying to view subscriptions list from vendor dashboard

This is from my Woocommerce error log:

(I think this is what you were looking for, though I have no idea what any of this is.)

No, that one is extremely expensive. In my other thread, I asked if it mattered what subscription plug was used for and the reply was no, so I’m trying this one: https://wordpress.org/plugins/xa-woocommerce-subscriptions/

If the Woocommerce-branded version is required, that’s a real hindrance – $199 per year is a lot to pay for this added feature.

Forgot to specify in my last reply – I’m using the premium version of the plugin I linked, which is found here: https://www.webtoffee.com/product/woocommerce-subscriptions/ (Much cheaper than the Woo option and already purchased, so I really don’t want to switch.).

Ok, so are you saying that in reality, we really SHOULD be using the Woocommerce Subscriptions plugin? Is the Subscriptions list on WCFM back end the only thing that isn’t going to work with the one I have? I was able to set up the test membership just fine using the WC Checkout option + the subscription plugin I listed. Does that mean it’s going to work, other than accessing the list from the WCFM dashboard?

Sounds fine. Thanks!

I just updated to the latest versions of all WCFM plugins and now my front-end won’t load AT ALL if I have the premium Woocommerce Subscriptions plugin activated that I mentioned earlier in this thread.
