Unable to approve new registrations

[cloudvps]

Since upgrading we are unable to approve new registrations.

When changing approved to 'yes' and saving, it says saves changed, however after refreshing the page it is defaulting to 'no'.

Anything we can do to sort this?

Hello.
Does the upgrade finish without errors? Have you upgrade versions one by one (1.3.0 > 1.3.1 > 1.3.2)
Clean your browser cache and check again. Look for errors in the AbanteCart error log

Everything seemed to update fine, no errors and yes it was done one by one.

This error is being repeated on the log since the upgrade:

Unknown Error: AbanteCart core v.1.3.3 Call to undefined function Symfony\Component\Mailer\Transport\Smtp\Stream\proc_open() in <b>/home/cloudvps/public_html/vendor/symfony/mailer/Transport/Smtp/Stream/ProcessStream.php</b> on line <b>41</b>

please check is your folder public/html/vendor exists.
If not - just copy it from our git repository (zip-archive)

Yes that was there.

We tried re-adding but still having the same issue.

Anything else we can try?
