Note, it is not really an error. It is an ALERT.

Ok thanks Scott. I had the same problem as cawoodwilly with the edit this theme, but did as he did and deleted all themes (after backing up to USB), and kept my current theme only. The 'edit this theme' has now vanished too.

All seems good after a preview of the site, but do we need to pay ourselves again to check paypal payments etc, or was this all untouched?

No changes were made to that area. You should also setup a PayPal Sandbox account. This would allow you to test PayPal without having to pay any fees.

Thanks for the info on paypal payments Scott. I don't mind if I get charged 30c to test, but to date, I have received all fees back on refunds from paypal.

Make sure of that return of refunds Bren, they don't document their removal of the 30 cents at all on your account, just the difference in the numbers will tell you. Pretty sneaky and sly if you ask me

Thanks Jo-Ann. I will be keeping an eye on it, but I'm pretty sure I did get all the fees refunded. I didn't really notice if my balance dropped by a little though.

Anyway, I received the new T & C from Paypal. I don't usually read this stuff , but due to all the differences with fees, I decided to use CRTL F to get past the blar, and found this about fees on refunds.

Refunds

13.11. You can refund a payment received to the sender within 60 days of the payment being received, by logging into your Account and following the prompts.

13.12. If a transaction is refunded, both the Fees and the payment will be refunded. If you return funds through the “Send Money” tab, this is not considered a refund and your transaction fees will not be refunded.

If you have that in your T & C, and it wasn't a "send money" option, then you should go back to Paypal.
