viktorB-17	Hello Team WPML, I have been trying to get my website to work for months now. I have hired multiple people to speed up my website and non of them could figure out why its not possible to speed it up. I have switched 3 Hosting provider - now I am on Siteground. I always got told the problem is because of my products have variations so they are probably heavy and load so slow. Only today we have finally tested if the performance is due to WPML: 1)I have moved all products to trash (except for default language) 2)And then i have deactivated all WPML plugins 3)cleared and loaded cache = Website has 99 score and loads super fast without WPML then tried it again activated WPML & restored products from trash its again super slow - not only products but every page loads slow especially products. Please help me out! Its been a few frustrating months and I feel like we can solve this soon. I would really love to keep using WPML as its just what I need to have multiple language stores. But in this state it slows down my website soooo much its not usable. I hope you have experience with this and could help me out - that would make my day, week moth and year! you can check any store front any especially paper cup products are very slow Best Viktor

Itamar WPML Supporter since 02/2016 Languages: English (English ) Timezone: Asia/Jerusalem (GMT+03:00)	Hi, Viktor. Here a few suggestions. Please try them. 1. Update WPML to its latest version - 4.6.7. You have version 4.6.6. 2. Deactivate our following add-ons. - Advanced Custom Fields Multilingual - it doesn't look like you are using the ACF plugin, so there is no point in using our glue plugin. - WPML CMS Nav - it is most likely you are not using this add-on. If this is correct, please deactivate it. - WPML Sticky Links - same as the above. - WPML Media - if you are not using different images per language, you can also deactivate this add-on. Also, please take a look at our guide on how to Prevent performance issues with WPML. https://wpml.org/faq/prevent-performance-issues-with-wpml/ By the way, I checked your site, and it loads pretty fast for me. For example, I switched to French for the Paper Cup product, which loaded in under 3 seconds. Please see the attached screenshot. Regards, Itamar.

Itamar WPML Supporter since 02/2016 Languages: English (English ) Timezone: Asia/Jerusalem (GMT+03:00)	Hi, and thanks for trying my suggestions. 1)I have no option to up update to 4.6.7 - there is no update avavilable for me You should be able to see that 4.6.7 is available by following our guide here. (see the section "How can I check for updates?") https://wpml.org/faq/install-wpml/#checking-for-updates If the problem persists after updating WPML to 4.6.7, please share with us WordPress's debug log (not WPML debug information). Please check this page for instructions. https://wpml.org/documentation/support/debugging-wpml/ To enable it, open your wp-config.php file and look for define('WP_DEBUG', false); Change it to: define('WP_DEBUG', true); // Enable Debug logging to the /wp-content/debug.log file define('WP_DEBUG_LOG', true); // Disable display of errors and warnings define('WP_DEBUG_DISPLAY', false); @ini_set('display_errors', 0); After this, repeat the action that causes the problem on your site (load a slow-loading page). In this case, the errors will be saved to a debug.log log file inside the /wp-content/ directory. Then please share the errors with us. Thanks, Itamar.

viktorB-17	I was reading through all the Support Forum Topics - but could not find any solutions to this. I noticed that a WPML Support person asked once for the plugin query monitor to be installed. So I did that too now and I am sending you a screenshot attached - for the product page it has 13s loading and 1300+ Queries. If it helps you and would speed up the process to find a solution - I can provide a admin login to my WP and to my hosting. Please let me know what what we can do to solve this. Best, Viktor

Itamar WPML Supporter since 02/2016 Languages: English (English ) Timezone: Asia/Jerusalem (GMT+03:00)	Thanks a lot, Viktor. I'm consulting our second-tier supporters regarding this problem. It may be that we will need a copy of your site. If needed, do you allow us to install a migration plugin like Duplicator or All In One Migration and take a copy of your site?

Itamar WPML Supporter since 02/2016 Languages: English (English ) Timezone: Asia/Jerusalem (GMT+03:00)	Hi, Viktor. Our second-tier supporter did find the cause of the performance issue. He found that with the copy of your site on his local server, there is a big performance improvement when he disables the following functions in the functions.php file of the child theme of your site. //add_action( 'wp', 'move_upsells_after_related', 1010 ); //add_filter('woocommerce_get_price_html', 'lw_hide_variation_price', 10, 2); //add_filter( 'woocommerce_ajax_variation_threshold', 'woocommerce_increase_variation_limits', 100, 2 ); Please try it on your site and see if it helps. ** Important! Please make a full site backup (files and DB) before you proceed with those steps** Regards, Itamar.

viktorB-17	Hello Itamar, Thank you for getting back to me. I have applied the changes - and i see a minor improvement. in the products load speed. But its no where close to how the website works without WPML if you only use one language. This is stil lvery slow and not todays standard. Unless you have a better slution to this - I think I wont be able to use WPML for this project. If you are not able to find a solution to this I would kindly request a full refund due to performance issues like you guarantee on your website. as stated in your performacnce guarantee :: https://wpml.org/faq/prevent-performance-issues-with-wpml/ Thank you for your help. Best Viktor
