Hey, @xavi74!

If I deactivate all plugins except WooCommerce and WooPayments and change the theme temporarily, will I not lose any of my settings when returning to my theme and plugins?

A lot of plugins will keep the settings stored, so they are still there when you activate them again.

Having said that:

— Be sure you have a good backup in place of your full site and database. You can ask your host for backup functionality or you can consider using a service like Jetpack. If something goes wrong, you will be able to restore it.

— Also, you can consider using a plugin like Health Check & Troubleshooting. This is a plugin developed by the WordPress community and it is helpful to disable plugins without affecting your current site visitors.

— It is important to consider as well a staging functionality in case you would not like to touch your production site (you can ask your host if they offer this service), or you can use WP Staging for quickly spinning up a new test site.

You can find more about this in this guide.

Please let us know about your findings.

Looking forward to your reply.

Have a wonderful day!

Hey, @xavi74!

I understand this is a frustrating situation, but I’m confident we can help you get to the bottom of it and find out what is causing the issue.

Were you able to run the conflict test?

Have you already tried placing a test order from a different browser to see if the issue persists?

Looking forward to your reply.

Have a wonderful day!

Hey, @xavi74!

I was doing some further research and I found some extra information on this.

A while ago, this issue was happening (it was fixed on a later version) and these were the workaround people used:

1. Using the checkout block instead of the shortcode.
2. Not marking optional fields as Hidden via the customizer.
3. Reverting to to a previous version.

Please try those to see if it help as a workaround. I’ll explain each one below.

1 – You mentioned “I’ve finally understood what I’m asked in the guide you’ve given me but I can’t add a cart block because it’s paid and I only have the free version.”

But the checkout block is not paid, it is free.

To change from the shortcode to the checkout block (if you haven’t already) you can go to Pages → Checkout. If you have the short code you should see something like this:

To remove it, select the block, click on the three dots and select delete.

To add the checkout block, click on the plus icon and search for Checkout. Then click on it to add it. And click on update.

Now you can check if the issue persists.

2 – To do this step you can go to Appearance > Customize > WooCommerce > Checkout

Then make sure nothing is mark as hidden and save the changes

3 – You can find older versions to download here. At the bottom, you can choose the development version.

If you prefer, you can also use a plugin such as WP Rollback to help you with this process. You can find the plugin here.

Please let us know hos this goes.

Now, as I mentioned those are all just work around. But we need to figure out what is causing this so we can work on fixing it.

Can you please share step by step with as many details as you can give us how you are triggering this error message. If you can also share screenshots, it is even better. I recommend using https://snipboard.io. You can share the direct link to the image as a response to this topic.

You mentioned you are able to proceed with cash on delivery, correct?

With which of the payment methods available do you get this error? Only regular credit card? Have you tried other any of the other methods available?

Looking forward to your reply.

Have a wonderful day!
