I am facing a very odd and frustrating issues in my product page that has something to do with Javascript errors mostly "cannot read properties of undefined ( classlist ) "
Its been more than a month and I have been running errands can’t really understand what is actually happening, so the thing is that customers who come to my product page and click “add to cart” then they are not lead to the /checkoout page instead the product page reloads and customer stays stuck in one product page long story short the add to cart button is not properly functioning for the customer they click and the product page just reloads but the button should lead them to the /checkout page as I have setup the button this way but no luck.
Secondly is that to better understand what is going on I installed microsoft clarity so it records customer sessions so I can see what is going on there I saw this button problem as explained above but something even more, during the session recording I saw clarity told me that there were several around 50 - 60 javascript errors in repeating pattern and that error was mostly 98% of the time "cannot read properties of undefined ( classlist ) " and then clarity also told me that this error might have impacted page functionality like buttons not working etc and also variant selection problem.
I am not sure how to fix this, the theme I am using is the basic free theme “Trade” so such errors should not come. What makes this super problametic is that when I do this no such error occurs button is working properly everything is working smooth the variants,buttons, pills the whole page is 100% working fine along with the entire website but only my customer who come from my native advertising platform where i run ads face this problem.
So only my customer face this problem, not me not anyone else everyone can place order in my store 100% working website but only only my customers who come from my ad compaign face this issue, maybe it has to do something with the pixel from the advertising platform? not sure
Please can someone assist me with this error I believe a Javascript and website development expert can fix this issue, I have so far burnt 600$ in ads with 0 conversions this bug is blocking all my conversions
Hi friend I recently faced this But I just have to firstly remove all the apps In installed that are not really essentials for me and then I changed the theme I was using the trade as well before but I switched to dawn and it is working perfectly by default You can try this
And In addition take time to make proper research and keep track on what works before investing in ads most of we shopify store owners do make this mistake and it cost alot
You absolutely need to share a link to your store.
Trade (together with other themes from the Dawn family) is used by thousands of stores and most of them work fine, so this must be specific to your setup.

Have you tried to follow your own ads to see if pixel breaks it for you?
Can you tell how others can try to replicate – what ad do needs to be followed?
Did clarity reported user agent of these sessions – were these standalone browsers or built-in browsers of the social net app?
These built-in ones can have their own quirks; but again, usually Trade works fine with those too.
Welcome to the Shopify Community! Please share your store URL and password (if it’s password-protected), so I can check and provide you with the exact solution.
But this is something fascinating. Come on dude… seriously? You misspelled your own name??? wtf
You should get rid of the fake Trustpilot badge (I know it’s from Gem Pages builder app), and the “125,632+ Satisfied Customers” crap. It’s fake. We all know it’s fake. Makes you look fake too.
Oh and having that ®️ is illegal. You certainly never registered any trademarks and this will get your store shut down in a heartbeat.
If these are the error you suspect, then these are for Announcement bar animation and these are not related to your cart/checkout not working.
This happens because you have entire header with display:none; – in this case you may as well hide the announcement bar section (by clicking an eye icon in Customizer), this will stop these errors.
(Your visible “announcement bar” is from Gem Pages)
This isn’t just a random JS error, it’s coming from a conflict between your theme header (set to display:none) and Gem Pages still trying to load its own announcement bar + scripts.
That’s why:
errors keep showing
fixes don’t stick
and your cart/checkout starts acting weird
Most people here are telling you to “send your URL” but the truth is this needs a proper structural fix, not trial and error.
I’ve handled this exact type of issue before (Gem Pages + theme conflicts), so I can:
trace the exact script causing the error
clean the hidden header conflict properly
and stabilize your cart + checkout so it stops breaking again
If you want, send me your store link (and preview if it’s locked), I’ll take a quick look and show you exactly what’s causing it before you decide anything.
you do know that this post was made few months ago, guess what? I created an entire new shopify store signed up with new email in hopes it gets fixed the page the ads etc is same obviously and still facing thiss issue
today 10 carts were added customer subscribed to my newsletter tried to make a purchase but /checkout never loaded for them
this is the product page where cusotmer clicks “add to basket” which should lead them to /checkout page
I had to read this 3 times and also checked the date to make sure it wasn’t April Fools.
Having fake reviews is not just ethiclly wrong, its misleading and if your thinking of having the business for a long run then its not a good look on your brand.
No worries, im just pointing out that business try to get people to trust the business but when people have a sense that it they cannot trust the business, it leaves a bad taste. They will start to question everything. It’s hard to earn people trust but its easy to lose them. Don’t let your hard work end up being for nothing.
