Product Not Added to Cart
When using WooCommerce, the Add to Cart form sends a long data string to the server. This data string represents the customized product thumbnail created by the Chamevo Product Designer.
In some cases, the product may fail to be added to the cart. Here are the most common causes and solutions:
1. PHP post_max_size Too Low
If your server’s PHP configuration has a small post_max_size value, it may not handle the long data string sent with the product.
Solution:
- Increase the value of
post_max_sizein your PHP configuration. - If you are not sure how to do this, contact your hosting provider.
- Our support team cannot adjust server settings on your behalf.
2. Server Blocking the Request
Some servers may block long requests by default. This prevents the customized product data from being processed correctly.
Solution:
- Check your server’s error log file for relevant errors.
- Contact your hosting provider for adjustments.
- Since this is a server configuration issue, our support team cannot provide direct fixes.
3. Workaround: Disable Customization Product Thumbnail
If increasing limits or fixing server configuration is not possible, you can disable the feature that sends the large data string.
Steps:
- Go to Chamevo **→ **Settings
- Open WooCommerce Settings
- Open Cart Menu
- Disable the option Customization Product Thumbnail.
- Save Settings
