Ok thanks for your help! Appreciate the input 🙂

Ok thanks for the explanation. I will look into it further my end 🙂

Ok thanks. So to properly serve adaptive images I would need to use Short Pixel Adaptive Images plugin instead of SPIO?

And still serve next gen images from AO via SP CDN?

thanks

Hi @lovingbro & @doublezed2

thank you for explaining this to me, helpful to narrow down the workflow even further. And yes its very clear that it’s a compatibility issue between the 2 plugins – which is bizarre when this function is only available with this plugin combo.

As to your questions – this issue has happened the entire time, there wasn’t a time when the duplication did not happen. It is a new site yes, and it happens on both the live site and the staging site. So its not any additional plugin conflict causing it and also doesnt get fixed on a fresh new wordpress.

And with a normal non-auction product, the New Order email and payment is all processed correctly with no duplication, so yes its an issue with how the auction plugin handles post-auction payment events and email triggers as you say.

Thank you!

Hi,

So the plugin FluentSMTP plugin is installed to show email logs, and yes the emails are being generated and duplicated. I have been given some php code to prevent the duplication of emails which did the job but it also stripped the recipient email field of those emails. See below the 2 screenshots showing these.

Email logs showing duplicates: https://snipboard.io/QAyuGp.jpg

Email logs showing no duplicates but recipient email field stripped: https://snipboard.io/4OXa9p.jpg

php code that prevented duplication is at end of this message.

Let me know what you think and if you want me to give you access to the staging site?

Thanks

Sam

Hi @kmacharia

thanks for replying to this and for the suggestion, but I already have an SMTP plugin configure to do exactly that. And yes the notifications settings are the same on both.

I have also now been told that this message is being shown when a user tries to submit the form on multiple attempts:

Just following up here – I have disabled the repcaptcha for now so the form can still work for the time being. But I do need this issue to be fixed please.
thanks again
