Shopping Cart Stopped Working

Hi, is the following error message what you are referring too?

Error! The price field may have been tampered. Security check failed.

If this site uses any caching, empty the cache then try again.

Do you have a cache plugin running in your site? If you do make sure you clear your cache and exclude the shopping cart pages from getting cached.

Kind regards

Yes, that is the error message and we do have a caching plugin. I did clear the cache yesterday, but didn’t exclude the shopping cart pages. I’m looking at the Page Cache in the plugin and can’t figure out where to add the shopping cart page to be excluded.

I disabled the cache for the shopping page which is actually the posts page. It didn’t work. Still getting the same error message. Can I revert to the previous version of the plugin?

Hi, can you share the shortcode you are currently using?

Also have you tried the plugin/theme conflict test? For example: Disable all other plugins except ours then carry out a test. If this does not work, try one of WordPress default themes like Twenty Nineteen, then carry out a test?

Here is a link to the previous version 4.5.0.

Let me know how you go.

Thank you

Using the previous version worked.

I’ll have to figure out when I can use the current version by the plugin test and not interrupt any sales on the website.

Here is the shortcode we use:

[wp_cart_button name=”Introduction to Metalsmith Basics:? Intensive ? ” price=”100.00″ var1=”Dates| October 17? 2020 10:00-1:00|November 14 , 2020 10:00-1:00|”]
[show_wp_shopping_cart]

On this post: https://www.studio34artists.com/introduction-metalsmith-basics/

I had the same error, and this happened when there are 2 spaces one after another in the name=”… field

@terri2uus, your shortcode does not look correct to me.

You can try the following shortcode. I have cleaned it up a bit.

[wp_cart_button name="Introduction to Metalsmith Basics:Intensive" price="100.00" var1="Dates|October 17, 2020 10:00-1:00|November 14, 2020 10:00-1:00"]

Please check the following documentation to learn more about using variation control in our plugin.

Let me know if the above helps.

Thank you

I don’t know if it’s any help but the update broke my cart too, I found that removing the “&” symbol from the shortcode fixed it.

Sorry for not getting back about this. My client had another problem on another item. I removed spaces between the quotation marks and it worked. ?? Thank you for the answers.

I am glad you managed to fix your issue ??

Enjoy the plugin.

The plugin has a bug with the following short code [wp_cart_button name=”Text1 Text2″ price=”200″]
When there are 2 spaces next to each other (between Text1 and Text2) the following message occurs :
“Error! The price field may have been tampered. Security check failed.
If this site uses any caching, empty the cache then try again.”

and nothing goes to the basket.
When replacing the 2 spaces by 1, it works without problem.

Thank you.

@wppatrickr, please create a new support thread. This one is marked as resolved.

Thank you
