Does your plugin is compatible with this version ?

Hi @MaxenceTP, sorry to hear that you have faced this issue.

Our team has tested the flow with the latest version of WooCommerce, but didn’t face any issue.
So, can you please share a temporary admin, ftp access so we can check and assist you with this.

Also, please do share how to recreate the issue for your site. While sharing the access, don’t forget to mark the response as private.

You need to test with products that have a vendor 🙂

Products without vendors doesn’t call MVX so it works.

@MaxenceTP, Thanks for sharing the access. Our team is looking into the issue on your end. Kindly provide us some time.

[MaxenceTP]

Thank you. I’d like to clarify a few points:
– This error only occurs when you create the order via wp-admin
– This version of the plugin is in production, so it’s breaking my site, it’s quite urgent

I have another error on my production site that I haven’t managed to reproduce in dev.
When a user places an order, there’s another critical error:

In the class-mvx-vendor-order.php file I’ve replaced :
$this->vendor_id = absint( $this->order->get_meta( ‘_vendor_id’, true) );
by the previous line :
$this->vendor_id = absint( get_post_meta($this->id, ‘_vendor_id’, true) );

And it seems to be working. Why is this a problem?

I don’t know how to reproduce this error, so unfortunately I can’t confirm it.

However, if you think it’s OK, you can close this post

[Sangita Support Squad]

The error message that you have shared was coming on the reviews tab of the vendor store page on the MultiVendorX 4.1.0 version. We have already added a fix for that in the latest 4.1.1 version.
So we are closing this thread.
If you need any help or face issues in future please create a new support ticket.
