Hey there,

I have been trying to fix my slow loading time on my website

I have install plugins such as Heartbeat control aswell, however that was ineffective.

Here is my most recent pingdom website test for reference

Are we able to fix this issue?

Best wishes,
Nirvan

Please, contact administrator
for this information.

Hi Eva,

Thanks for your response.

I have read through the websites – which outlined steps that I have already undertaken – and also installed a variety of applications to the WP, which did not work, and now are uninstalled again.

The main issue seems to be the “Admin-ajax.php” file in the system, as it takes several seconds to process.

Would appreciate your help!
Thanks a lot!

Hi Eva,
Happy new year. I am writing this ticket under this support forum because our hosting discovered an error with the admin-ajax when we launched a new product on our site that caused a site outage.Even though there are only about 200 visitors on the site, the site crashes due to an unusually high number of hits to the admin-ajax.

Could you please help to figure out if it is an error in the theme?

This is the action hitting admin ajax that is still causing intermittent timeouts [action] => et_refreshed_fragments
These are all the files referencing that action:
plugins_updated/woocommerce/includes/class-wc-ajax.php themes/legenda-sub/js/etheme.js themes/legenda-sub/framework/woo.php themes/legenda/js/etheme.js themes/legenda/framework/woo_old.php themes/legenda/framework/woo.php plugins/woocommerce/assets/js/frontend/cart-fragments.js plugins/woocommerce/includes/class-wc-ajax.php plugins/woocommerce/includes_back/class-wc-ajax.php

Here are the quantities from that day for top hits:
22390 [action] => et_refreshed_fragments
1310 [action] => heartbeat

The host narrowed down this admin_ajax call to the shopping cart display on every page of the site. That’s going to require an admin-ajax call for that information on every page which takes up a lot of server resources.
Another thing they noticed is that it looks like there may be a typo in the theme.

The adminajax call that’s hugely populating your site is the et_refreshed_fragments action which seems to be coming from your theme. However, WooCommerce has get_refreshed_fragments with the g there.

I can also attach a screenshot with the showing the hits to the admin ajax.

Please let me know if you require additional information or clarification at all.

Thank you,
Sharon

Hi Eva,
We disabled the Heartbeat monitor already as in this article: https://www.inmotionhosting.com/support/website/wordpress/heartbeat-ajax-php-usage#heartbeat-in-action

Yet the site is still having issues. Do you have any more ideas – and can you be more specific rather than providing a general response?

Thank you,
Sharon

Hello,

We’ve improved our theme as much as we could. And we have already emphasized if someone of our customers has experience in development and has proposals concerning changes in the theme (we mean only specific changes in the code in particular files, rather than general phrases like “Reduce CSS File” etc), we are asking to declare them here or contact us via the contact form https://www.8theme.com/contact-us/

Please take our apologies but for now there are no more possibilities to improve theme loading.

Thank you for understanding.
Regards,
Eva Kemp.
