Can’t use version after 4.5.4

Hi, thank you for reaching out to us.

Unfortunately, the last version I can use is 4.5.4. If I update to a newer version, it doesn’t show in shopping cart.

There might be a conflict with one or more of your plugins and or theme.

What PHP version is running in your server? What WordPress version is running in your site? The reason why I am asking this is because version 4.5.4 is very old. Are all of your plugins and them up to date?

What shortcodes are you using?

Kind regards.

Please let us know if you are still seeing an issue with this.

PHP 7.4.10

version 4.5.4 works fine. After update to 4.7.1, I got following error:

Fatal error: Uncaught Error: Call to a member function get_name() on array in /hermes/bosnacweb02/bosnacweb02cb/b1855/ipg.geosuite3dcom/geoadvanced/wp-content/plugins/wordpress-simple-paypal-shopping-cart/wp_shopping_cart.php:409 Stack trace: #0 /hermes/bosnacweb02/bosnacweb02cb/b1855/ipg.geosuite3dcom/geoadvanced/wp-content/plugins/wordpress-simple-paypal-shopping-cart/wp_shopping_cart_misc_functions.php(14): wpspc_cart_actions_handler() #1 /hermes/bosnacweb02/bosnacweb02cb/b1855/ipg.geosuite3dcom/geoadvanced/wp-includes/class-wp-hook.php(310): wp_cart_init_handler(”) #2 /hermes/bosnacweb02/bosnacweb02cb/b1855/ipg.geosuite3dcom/geoadvanced/wp-includes/class-wp-hook.php(334): WP_Hook->apply_filters(NULL, Array) #3 /hermes/bosnacweb02/bosnacweb02cb/b1855/ipg.geosuite3dcom/geoadvanced/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #4 /hermes/bosnacweb02/bosnacweb02cb/b1855/ipg.geosuite3dcom/geoadvanced/wp-settings.php(632): do_action(‘init’) #5 /hermes/bosnacweb02/bosnacweb02cb/b1855/ipg.geosuite3dcom/geoadvanced/w in /hermes/bosnacweb02/bosnacweb02cb/b1855/ipg.geosuite3dcom/geoadvanced/wp-content/plugins/wordpress-simple-paypal-shopping-cart/wp_shopping_cart.php on line 409
There has been a critical error on this website.

one of the shorcode:

$695.00 [wp_cart_button name=”GeoSuite^?? Personal License” price=”695.00″]

If you need to use certain special characters in the product name, then do the following:

Go to the settings menu of the plugin and Check the following checkbox then save the settings.

Disable Price Check for Add to Cart

I updated to 4.7.0 and unchecked “Disable Price Check for Add to Cart”. I got a message “Error! The price field may have been tampered. Security check failed. If this site uses any caching, empty the cache then try again.”

I updated to 4.7.0 and unchecked “Disable Price Check for Add to Cart”.

You have to check this feature “Disable Price Check for Add to Cart” or else you will get the same error message. If you are running a cache plugin in your site make sure the following feature Disable Nonce Check for Add to Cart is enabled as well.

Let me know how you go.

Kind regards.

Is the Disable Price Check for Add to Cart checkbox checked or unchecked? Please make sure that it is checked/ticked.

Version 4.7.0

With ?Disable Price Check for Add to Cart?checked:

There has been a critical error on this website.

With ?Disable Price Check for Add to Cart?unchecked:

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

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

Version 4.5.4

With ?Disable Price Check for Add to Cart?checked: works

With ?Disable Price Check for Add to Cart?unchecked:

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

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

Did you also checked the following feature?Disable Nonce Check for Add to Cart? Enabling this features helps when you run a cache plugin in your site. Also make sure you clear the cache in your browser and or your site if you are running a cache plugin.

If none of the above steps helps you, then I suspect there might be a conflict with one of your other plugins or your theme. Please carry out the following troubleshooting steps.
