Failed order using PayPal standart

[promailer]

Good day, dear support. I have updated to the latest version of AbanteCart 1.2.10 few days ago. After the updates the problems started. Many of my orders are coming back with error:
"Failed or missing response from payment verification. Manual verification is required! this link". And as of today its not possible to make payment at all. Every single check out end with the following error - "Things don't appear to be working at the moment. Please try again later.".
I have triple checked all the data entered in the extension settings and in my PayPal account. The E-Mail address is the same in both places. Please assist me with this problem as my hands are tied on this one .

I wonder who do you refer to as support ?
There is no support in the forum.
There is a community help.

Back to your issue. I doubt that this is related to your settings.
Did you try to install new AbanteCart in parallel and try your settings? I suggest you do this.

I have had a similar problem that started this morning.  I was able to switch to paypal express however the standard paypal still yields an error (BAD_INPUT_ERROR)

Nothing had changed in 24 hours.  One day I was able to process orders - the next that error.  Looks to be the same as above.

Yes. At the moment my option is also to switch to paypal express .

Update! After going to v1.2.11 PayPal standart is working fine again. Thank you.
