Hi, WPML slows down my Woocommerce pages such as product pages significantly. I have all plugins deactivated and only Woocommerce and WPML activated. When both are active, loading product pages takes up to 20 seconds. When I deativate WPML (only Woocommerce is active), product pages load within 5 seconds. The same problem was described here: https://wpml.org/forums/topic/wordpress-and-woocommerce-product-page-slow-down-so-much/ however there was no solution presented by WPML. Please advise urgently as my shop is performing badly and I'm loosing sales because of WPML!!!! Frank

Hi Frank,

Is this issue happening with all product pages? If possible share a product page with me so I can make sure we are both testing the same page in order to remain consistent.

Also, is this happening in the backend/edit area or the front end?

I would like to request temporary access (wp-admin and FTP) to your site to test the issue.
(preferably to a test site where the problem has been replicated if possible)

**Before we proceed It is necessary to take FULL BACKUP of your database and your website. Providing us with access, you agree that a backup has been taken **

I often use the Duplicator plugin for this purpose: http://wordpress.org/plugins/duplicator/
You will find the needed fields for this below the comment area when you log in to leave your next reply.
The information you enter is private which means only you and I have access to it.

NOTE: If access to the live site is not possible and the staging site does not exist please provide me with a duplicator package created with the duplicator plugin.

Thank you,
Bobby

Hi there,

Thank you for the access details, I've reviewed this and can confirm that the performance is increased beyond what would be expected for a site with just 2 languages and not over 1,000 products.

Load time fluctuates between 11s - 16s at it's worst.

Running WPML optimizations and troubleshooting actions has no effect.

Recommend next steps:

0. Update WC to it's latest version (done already)

1. Increase WP MEMORY LIMIT to 512M from 40M - 40M is below our minimum requirements. (done already)

2. Downgrade PHP version to 8.2 or 8.3 if possible.

8.5 is not currently fully supported by WPML and also in beta support for WordPress.

There are numerous deprecated messages - these alone can cause performance issues.

After downgrading the PHP Version let me know your results please.

- NOTE that deactivating WPML causes a fatal error with WooCommerce, I am certain this is related to the PHP Version therefore I am not able to get the baseline performance to compare with WPML deactivated.

Hi Bobby - I changed PHP to 8.2. and deactivated everything but Woocommerce. The site loads within 4-5 seconds without WPML. So there is a significant difference in loading time due to WPML. Please advise! Frank

Thank you for updating me!

With WPML there is an increase of roughly 4s.

Below are the actions I did. #1 seems to have helped the most.

1. WPML->String Translation -> Auto Register -> set to " Disable auto register of untranslated strings\"

2. WPML_>Languages-> Make themes multilingual -> deactivate

3. WooCommerce -> WCML -> Status -> Troubleshooting
Cleanup tools
Remove unused custom fields from product and variation translations

This action times out eventually.

I am escalating this further and will update you as soon as I have feedback.
