[Resolved] Plugin causes problems on my live website

Hi,

Thank you for contacting the support. I am assigned this ticket and 'll try my best to help you on the matter.

Reference to your chat with Shekhar, I visited hidden link and added this to cart, then viewed the cart and went to checkout page. And I didn't run into any error.

I also tried to login to your site based on the information you provided, to check for any anomalies. But looks like access has been revoked.

However, please let me know if you are still facing the problem.

Also provide debug information of your website for an overview of your setup? See https://wpml.org/faq/provide-debug-information-faster-support/ for more information.

I've enabled the debug information section for your next reply.

Additionally you can also take a look at https://wpml.org/faq/checklist-before-opening-a-ticket-in-wpml-support/ and cross-check for a few initial fixes.

Hi,

We've just had this chat between you and me.

You didn't reply for almost 15 minutes, so I closed the chat. But I'll continue to help you here in this ticket.

The issue seems to happen randomly because now I can add the following product to the cart. Please see the attached screenshot.

hidden link

Can you confirm that it is a random issue that sometimes happens and sometimes not?

I tried to access your site to check things, but the access details you provided them do not work for me. Please see the attached screenshots. Please correct the access details and share them with me in the following private message.

If you need further help with this, please share the access details to your site with me.

Thank you for the updates. I'll be handling this ticket because Itamar is on vacation for some time.

May I ask for admin access to your website to check the issue in detail? You can create a separate admin user for this purpose, which can be deleted afterwards.

Also provide detailed steps to reproduce the issue and links to pages in admin and on frontend.

Remember to take full backup of your website and database before proceeding. However, a staging/test site is highly recommended, because I may need to try some changes/fixes on the site (including plugins & themes deactivation), which may cause conflicts with the live site otherwise.

Please confirm it in your next reply or let me know if you do not agree with the mentioned.

I've set your next reply as private to share this information safely.

IMPORTANT: If you don't see the section for providing access information, do not write in the message box or the information may appear as public.

Thank you for your patience and cooperation.

The issue was coming due to Query Monitor plugin, which is setting for some reason locale to null for some reason in the submission. Deactivating it fixes the problem.

I can now add products to the cart without any problem.

Query Monitor is running only for Admins. It is not recommended to keep it active on a live site because it is known to add additional load and performance surplus to the site. Only activate for debugging.

Please check and confirm.
