Product Page isn’t loading correctly – jQuery undefined

Hi @drbuzzz,

Just to check, are you using any caching/optimization plugins? If yes, please disable them and try reloading the page on an incognito/private browser window.

If the above does not yield any positive results, kindly try doing a conflict test to see if the issue persists when you’re running only the WooCommerce plugin on a default WP theme like Twenty Twenty One. Here’s the conflict test guide – https://docs.woocommerce.com/document/how-to-test-for-conflicts/

Let us know how it goes.
Thanks.

Thanks for your reply. I did the conflict test with the guide, but it didn’t help. The thing is, that it works on every single product, but not on this one. I’ve had this mistake a few times, and it’s really annoying. It seems that it only occurs on new products that I create. And as I said, the console is full of “jQuery is not defined” errors. What should I do?

Hi there,

Thanks for getting back to us.

Let’s see if there is an error on the WooCommerce Logs. Kindly provide us the following:

• System Status: You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”. Once you’ve done that, paste it here in your response.
• Error Log: Share a copy of any fatal error log found under WooCommerce > System Status > Logs (if available).
• Console tab: Right-click on the page or press F12 on the keyboard and select “Inspect” (this option will show up on most browsers). In the developer tools that will pop up you should see a “Console” tab. From there, please send us a screenshot of what’s being displayed using a tool like snipboard.io.

Thanks!

Hello,
thanks for the answer. Here is what you asked for. I couldn’t find an error log, so I guess it’s fine.

Thank you for your help!

Hi @drbuzzz,

Looking at your system status report there are several things that could be causing this including caching and also the OceanWP theme which is overriding the default WooCommerce template files of products from within the theme.

When testing on your site it seems like a possible Javascript conflict is preventing the images from loading. I noticed that something on your site is setting the opacity of the image to be 0.

Image Link: https://cloudup.com/ct5KDt6Xn2J

On all of my test installations, the opacity is automatically set to 1 and not 0.

Image Link: https://d.pr/i/t0ijei

There are also many other differences in the code output on your site relating to the image display too when comparing that to a default installation of WooCommerce using the Twenty Twenty-One theme or our own Storefront theme. It seems something installed on your site is possibly preventing the flexslider javascript the image galleries use from working correctly.

From what I’ve seen I’d suggest carrying out a conflict test again as what you’re experiencing is not directly related to the WooCommerce plugin itself from the results of my cross-testing for us.

To carry our a full conflict test on your site you will need to disable all other plugins aside from WooCommerce along with switching to a theme like Storefront. This will help with trying to and locate what software you have installed which could possibly be causing this behaviour? You could use a free plugin called Health Check and Troubleshooting to carry out such testing.

When in Troubleshooting mode all plugins will be deactivated and only the admin of the site carrying out the troubleshooting would see those changes. Any customers visiting the site would see no changes at all.

Once you have disabled all other plugins and switched themes if the behaviour is resolved you can then enabled your theme and sites plugins testing after each one is enabled until the behaviour returns to locate the culprit.

https://docs.woocommerce.com/document/how-to-test-for-conflicts/

Okay, I did the conflict test again multiple times, and it seems, that the problem is the AliDropship Plugin I bought a few weeks ago. It causes the error messages. But the Plugin costed $89, and I really need it for my store. What should I do?

Thank you for your help, so far!

Hi there!

I would recommend reaching out to the developer of the AliDropship plugin and let them know what is happening. You could link them to this thread. Hopefully they will be able to make an update to their plugin to resolve this issue.

You’ve referenced a commercial/premium plugin, so please use their official support channel. We feel they are best equipped to support their products.
