Transactional mails with attachment issue

Hi @jeromem_net,

Thank you for your message. We have performed a live test on our WordPress Sendinblue plugin and received a mail with attachments so we have been unable to replicate your issue.

So we can look into this for you please create a support ticket through your Sendinblue account or email us at [email protected] and provide us with admin access to your WordPress account (login url, username and password) and refer to this forum thread.

Please also provide a detailed description of the issue you are facing, including screenshots where possible.

We look forward to hearing from you and assisting you with your request.

Best regards,

Hi,

Many thanks for the quick reply and the live test.
I’ll contact you by email to give a detailed description.

@neeraj_slit any updates? Our plugin WooCommerce PDF Invoices & Packing Slips attaches PDF files to emails and some of our customers are experiencing the same issue.

Maybe the topic should not be marked as resolved as the issues still exists (with plugin used both by @pomegranate and me).

Investigation in progress (with help of the support, thanks).

@neeraj_slit Since someone else reported that switching back to 3.0.8 fixed the issue, I compared 3.0.7 to 3.0.9 (3.0.8 was no longer available on www.ads-software.com), and found this:

(full size)
It seems to me that this change was made in error and quite likely that this was the cause for the bug?

it would at least be worthwhile to test changing this back to:

$data['attachment'] = $attachment_content;

resolves the issue!

source:
https://plugins.trac.www.ads-software.com/browser/mailin/tags/3.0.9/sendinblue.php#L974

Just noticed that 3.0.8 is available but incorrectly tagged as 2.0.8:
https://downloads.www.ads-software.com/plugin/mailin.2.0.8.zip

There are two changes here that could be causing this issue, the first is the one I mentioned above:

3.0.8 (source):

$data['attachment'] = $attachment_content;

3.0.9 (source):

$data["attachment"] = array($attachment_content);

and also this:

3.0.8 (source):

$struct[ $filename ] = $file_buffer;

3.0.9 (source):

$struct["name"]     = $filename;
$struct["content"]     = $file_buffer;

I hope this will help in shortly resolving this issue!

@pomegranate Thanks a lot, it is very kind to help debugging plugin from others developers.

We’ve identified that this issue occurs when the ‘PDF Invoice’ plugin for WooCommerce is used in conjunction with the “Transactional emails” option in our WordPress Plugin (the full name of this plugin is ‘Newsletter, SMTP, Email marketing and Subscribe forms by Sendinblue’). We will fix this issue as a priority in an upcoming release.

The solution for the time being is to go into the settings for our WordPress plugin and set the “Transactional emails > Activate email via Sendinblue” option to no. Then, activate the same option in the Sendinblue plugin for WooCommerce (full name ‘WooCommerce Sendinblue Newsletter Subscription’). You’ll find this option in WooCommerce settings > ‘Sendinblue’ tab > ‘Enable Sendinblue to send WooCommerce emails’.

This solution will allow users to continue sending ‘PDF Invoice’ invoices via Sendinblue until we are able to release the appropriate fix. We apologise for the inconvenience and appreciate you bringing the issue to our attention. I’d like to especially thank @pomegranate for all the information shared here.

@neeraj_slit thanks for the temporary solution. Note that this not only affects PDF invoices, but all emails with attachments:

• Contact form 7
• Appointments plugin
