Lightbox not working despite added code

`<?php add_action( ‘after_setup_theme’, ‘yourtheme_setup’ );

function yourtheme_setup() {
add_theme_support( ‘wc-product-gallery-zoom’ );
add_theme_support( ‘wc-product-gallery-lightbox’ );
add_theme_support( ‘wc-product-gallery-slider’ );
}
?>

You should add in the code in your functions.php file below the line where it says “add_action”.

If you’re uncomfortable working with the functions.php file, recommend using the following plugin to manage your snippets:

I was hoping to do that in a way that would not be affected during upgrading the theme.

But that plugin looks perfect. Thanks!

I added it in and there was a conflict with the mu-plugin code which implies to me that mu-plugin code should work. I’ll remove the code in the mu-plugin anyway and try it.

No.. it still didn’t work.

add_action( ‘after_setup_theme’, ‘ArtToCanvas_setup’ );

function ArtToCanvas_setup() {
//add_theme_support( ‘wc-product-gallery-zoom’ );
add_theme_support( ‘wc-product-gallery-lightbox’ );
add_theme_support( ‘wc-product-gallery-slider’ );
}

This is version 3.4.1 on WordPress 4.9.6

If you copied and pasted that code snippet as it is, it has typographer’s quotes rather than straight quotes so I would encourage you to take a look and ensure that the quote marks are all straight quotes rather than typographer’s quotes.

I made sure that it has straight quotes and it still doesn’t work. Thanks for thinking of that but it’s not that.

@george18sa Deactivate Autoptimize and see if that fixes it, there are JavaScript errors on your product page that may be due to many JavaScript files being condensed into one.

pro-tip; you can disable Autoptimize on a per-request basis by adding ?ao_noptimize=1 to the URL.

if the problem is not there at that point, some autoptimize (re-)configuration might be needed to fix this. there’s more info in the troubleshooting tips and info on exclusions in the AO FAQ.

hope this helps debugging,

^^ That didn’t fix it, but it removed the JS errors.

I just installed AutoOptimize recently—this was happening before.

And I noticed the javascript errors. It’s just the way the site was put together (before I showed up) that’s so bulky and shows up terribly on GTMetrix.

So I’ll turn it off again for now to lose those errors but what can I do to fix that gallery? ??

Taking at look at this. It looks like this is an issue with the theme. Can you supply the status page from Woo?

WooCommerce > Status and copy/paste that log here? I have a feeling the theme is overriding the template and removing what actually allows it to work.

Regardless if that function/filter is active and tells WooCommerce that it can do it. If the template has been either overridden or modified via actions/filters it simply will not function.

If you change your theme to say Storefront or Twentyseventeen does the lightbox work?

This is what I get : 2018-06-07T14:50:06+00:00 CRITICAL Allowed memory size of 268435456 bytes exhausted (tried to allocate 1048577 bytes)

Also, this wordpress installation is so heavily customized that I’m afraid to change the theme.

However, there is this : the theme contains outdated files even though I have updated Woocommerce to 3.4.1. Could this be the problem?
