[Resolved] Javascript error that jQuery is not defined

[Michael]

Hello guys,

I’m having a problem with jquery which I found out about because my Site Reviews plugin stopped working correctly. I wrote to the developer and he said that “there is a javascript error that jQuery is not defined. Site Reviews does not use jQuery, so this is coming from something else.” So I have been looking on Google and found this page:

https://kinsta.com/blog/jquery-is-not-defined/

I am on the last suggestion “Method 5: Insert the jQuery Library Manually”. Unfortunately I cannot make sense of this, but I gather a change must be made to header.php in the theme which in my case is generatepress. Please could you assist? Many thanks.

Michael.

Hi there,

this either means that jQuery is NOT being loaded on your site. Or theres a script that has jQuery dependencies that is being executer before jQuery has been loaded.

Do you have a link to a page where this error occurs ?

Thank you very much for your time David. The issue happens with the site reviews plugin on our shop page here:

https://reclaimdesign.org/home-decor-shop/

If you scroll to the reviews section and click 1 2 3 Next the next reviews page never shows it just displays a spinning animation and doesn’t get past this.

This is what the console generated when I clicked the next button:

his page uses the non standard property “zoom”. Consider using calc() in the relevant property values, or using “transform” along with “transform-origin: 0 0”. home-decor-shop

Ok, see here:

Looks like ECWID is trying to use jQuery before the script has loaded.
It may be because ECWID scripts are being preloaded.
Check with ECWID support as fixing that issue will mean the browser can resume executing scripts that fire afterwards.
