Customer order errors

Hi @danvoz,

Thanks for reaching out. This does sound like an unusual situation and is definitely worth looking into more closely. To better understand what might have happened, could you help us with a few details?

• Is the product type simple, variable grouped, etc?
• Does the product in question have any discounts set at the product level (sale price, scheduled sale, etc.)?
• Could you check under Marketing → Coupons to confirm there are no active, expired, or user-specific coupons that might have been triggered?
• Do you have any third-party plugins like membership, dynamic pricing, or wholesale pricing plugins that might have interfered?
• Could you share a screenshot of the affected order, especially the order summary, shipping lines, and any coupon/discount section? You can use https://snipboard.io/ to upload and share the link here.

This will give us a better view of whether something like a coupon was applied programmatically or if there’s something in the order metadata that might give clues.

Now, while we’re waiting for that info, here are a few possibilities worth keeping in mind:

For the dual shipping methods:

• There might be overlapping conditions in your shipping zone settings that allowed both methods to appear at once.
• A plugin or theme customization could have interfered with how the shipping method was stored.
• It’s also possible the customer’s browser had cached or conflicting session data that affected how the checkout worked at the time.

For the 0 CZK pricing:

• There could be an old or hidden coupon that applied automatically.
• The customer’s user role may have triggered a discount via a third-party plugin.
• There may have been a temporary conflict or glitch caused by another plugin that affected how prices were processed.

Once we have those details, we can help dig further. Looking forward to your response. 

Hi there!

Thank you for sharing the screenshot and the system status report. I’ve reviewed the details, and everything appears fine overall. However, I did notice that the product was 100% discounted.

For the shipping-related issue, the Zásilkovna or Payment Gateway Based Fees and Discounts plugins could potentially interfere with the shipping logic.

Also, the coupon or pricing behavior might be affected by plugins like Code Snippets, StoreCustomizer, or Order Export/Import, especially if they include custom functions. To assist you further could you please go to WooCommerce → Status → Logs, and check for entries around the time the order was placed.

While we can’t say for sure which plugin caused the issue, it’s likely due to a conflict or a caching-related glitch. Since it only happened once, it might have been a one-time event.

Please let us know if it happens again!

Hi there!

Thanks for checking the logs — the error from the PDF Invoices plugin suggests something may have gone wrong during order processing, though it doesn’t directly explain the duplicate shipping or 0 CZK price issue.

Since this seems to be an isolated case, I recommend keeping an eye on future orders and letting us know if the issue happens again. If it does, please check whether there’s anything in common across those orders — for example, the same customer, country, product, or shipping method — as that can help narrow down the cause more quickly.
