The second issue that might be a cause for your missing Add-to-cart button is the incompatibility between plugins and themes. There is no denying that using more plugins means you are more likely to encounter compatibility issues. To be more specific, this often happens when you update WordPress, change your plugin version, or update WooCommerce.

Step 1: Check if plugins use the latest versions

This is to say, it is necessary to check whether you are coping with conflicts between themes and plugins or not. First of all, you need to make sure that all plugins you are using need to be updated to the latest versions.

Step 2: Clear the site cache

After that, you are supposed to clear the site cache. To do this, you will log into the cPanel of your website and head to the section “PHPMyAdmin”.

In case, the hosting plan you are using is a shared one, you have to navigate under the section “Databases”.

Clear the site cache

In case, the hosting plan you are using is a premium one such as Kinsta, you can explore PHPMyAdmin by scrolling under the website info section. When you cannot find the tab PHPMyAdmin, you should contact your website hosting provider to ask for support.

Clear the site cache

After opening the PHPMyAdmin, you could notice a list of multiple tables. Proceed to choose the table of post meta in WordPress. Wp_postmeta will be the default name of that table. In this situation, you should use the customized table prefix to have better security.

Step 3: Disable plugins to identify the cause

Now it is a need to disable all plugins on your site to identify which plugin leads to this compatibility issue. We think that you should implement it in bulk to save time and effort. Especially, disabling plugins in bulk is also effortless. You just need to go to the backend of your WordPress. Next, head to the “Plugins” and choose “Installed Plugins”. Here, you could notice all plugins that had already been installed as well as activated on your website.

Disable plugins to identify the cause

3. Fix the incomplete information of WooCommerce products

Incomplete information of the product in WooCommerce is also a common cause to result in the Add-to-cart missing. Hence, when you are in doubt of this cause, do not hesitate to fix it as soon as possible. This cause is usually overlooked, so do not miss this one as this button will not work if your products are incomplete information. For example, you have not filled in the product name or price.

5. Cope with Unwanted cache setup issues

This section will let you know one more cause for the missing Add-to-cart button: the issues with unwanted cache setup. Elements causing problems to this button can be the ones with your site caching your Checkout, Cart, and My Account pages. As those pages host only dynamic content, you are advised to rest assured that the cache plugin should come with URLs for those pages excluded. This explains why cache plugins should be used to create exclusions for specific URLs.

Cope with Unwanted cache setup issues

Furthermore, in case you have the setup of one server-side cache, you should be sure of excluding those URLs. If you are not certain about how you could perform it, do not hesitate to contact your hosting provider to seek help and support.

One more not-to-be-missed reason that should be prioritized when it comes to the improper working of the WooCommerce Add-to-cart button is problems related to permalinks. As you may know, the permalinks could result in unexpected issues on your Shop Page. Hence, they could enable your Add-to-cart button to break off. This is to say, flushing them is a nice idea.

To do this, you will go to your WordPress dashboard, then navigate to the section “Settings” and choose “Permalinks”. After that, do not forget to save what you have made recent changes.

Handle problems related to permalinks

Some users are keen on changing the settings to ensure that permalinks are all kept updated. And in this situation, you need to choose the section “Plain” or the Radio buttons below the option “Common Settings”. Next, proceed to hit on “Save Changes”. When everything is okay, it is time to change them back to the initial setting you used to have. And save these changes one more time.

This activity aims to update all the permalinks and assist you in fixing issues related to your Add-to-cart button.

7. Fix Checkout & Cart URL issues

It is also necessary to check if your WooCommerce site has any problems with the setup of Cart and Checkout pages. Remember to double-check them meticulously. In case the Add-to-cart button works by redirecting your customers to the wrong page, this indicates that it doesn’t work properly.

Fix Checkout & Cart URL issues

In checking this issue, you need to head to your “WooCommerce” and click on “Settings” before selecting “Advanced”. You then need to check if you have set up the right pages below your Cart, My Account, and Checkout pages or not. If not, make sure you did it.

8. Fix checkout endpoint issues

The next issue that might happen to your site is errors with your checkout endpoints. This means that you should make sure that there is nothing wrong with your checkout endpoints. It is of great significance because if these endpoints are not properly set up, they will result in the wrong operation of your Add-to-cart button.

Fix checkout endpoint issues

Now it is time to check these checkout endpoints according to your “WooCommerce” as per requirements then choose “Settings”. Move on to select the option “Advanced” and “Checkout endpoints”. After that, it is a need to check if any spaces exist in your endpoint URLs. If had, remove these spaces to avoid any unexpected endpoint errors.

9. Tackle Code problems

Code problems are also one of the most common issues to make your Add-to-cart button stop working. There are a lot of cases your WordPress is subjected to code issues, primarily when you have implemented to customize it. To be more specific, relevant instances to codes involve pricing problems for the variable products. In such situations, WooCommerce disables this Add-to-cart button on issues with the default variable pricing or variable pricing.

To fix this problem, you are required to add the below code to the file functions.php. In opening that file, you simply head to the section “Appearance” then click on “Theme Editor”.

Tackle Code problems

The next step entails pressing on the file functions.php that lies in your right sidebar. When you are here, your next task is to paste the below code snippet to the file’s end in the section editor, then choose “Update File”. The final thing to do in this section is to check whether you have finished fixing this issue or not.

add_filter('woocommerce_show_variation_price', function() { return TRUE;});

10. Check theme issues

Besides the above issues, theme issues should be also considered because they might be the underlying causes to make your Add-to-cart button work improperly. When you are applying one WooCommerce theme, this may have dedicated features for product pages. As a result, it could hide your Add-to-cart button as well.

So, spend time checking it as soon as possible in case it is one of the options on your WooCommerce theme. To execute this activity, you need to head to the section “Appearance” and click on “Customize” before choosing “WooCommerce”. When you are here, proceed to check the available options that are for your product page.

Check theme issues

Moreover, when there exists a conflict that happens to the WordPress theme as well as the product pages, or your Add-to-cart button is not properly loading because of template problems, it is possible for you to tackle it with the use of a super simple script. By opening the section “Theme File Editor”, you could press “Appearance” and choose “Theme Editor”. Keep going by selecting “Single Post” under the files “Theme” on the right sidebar. After that, you need to paste the following code to the end of the file single.php. Be noted that if you can’t find the file single.php, you will paste the below code snippet below index.php.

if ( is_singular( 'product' ) ) {
wc_get_template_part( 'content', 'single-product' );
} else {
wc_get_template_part( 'content', 'single-product' );

11. Check ModSecurity Problems

Problems with ModSecurity also cause some unwanted issues for your Add-to-cart button. So, you need to check it to identify whether it results in issues or not. It might be due to the expiration of ModSecurity, leading to the improper operation of your WooCommerce Add-to-cart button. By going to your site and opening your browser’s developer tools, you can check if your ModSecurity has issues or expired.

If you detect the error called “.jQuery.cookie.min.js is not found”, that is the issue with the ModSecurity. In fixing it, you should contact your site hosting provider to seek help and support from them.
