Compatibility with WooCommerce Issue

    When I have Ewww Image Optimizer activated along with WooCommerce. I experience this error when purchasing a product on my site. It happens in the final stage when I click “place order.” This is the error at the top of the page:

    SyntaxError: Unexpected token < in JSON at position 0

    I tried deactivating all my pluggins one at a time to try and figure out if another pluggin was causing the issue and this only happened with Ewww.

    Any thoughts on why this is happening would be great! I’m a big fan of Ewww Image Optimizer and would hate to not be able to use it!

    If you don’t have it, install Firebug extension for Firefox, open the Firebug console, make sure it is logging AJAX requests. If you’re in the admin side of WP, you’ll be seeing periodic “heartbeat” requests.
    Then, do the same thing, and see what the ajax response is that causes problems. I suspect there is some error message being output, when WooCommerce is expecting a json response.

    A second thought, are you using the Alt WebP option?

    It looks like all of the ajax requests are coming back with a Green 200 ok mark (sorry I’m newer at this so my lingo might not be up to snuff).

    And no, I’m not using the WebP option.

    Update:this is the error I got when I tried it again in firefox (not chrome like my initial post):

    SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

    Ok, if you’re using Firebug, you can click the little plus symbol to expand the request, and see the actual response, that should shed some light on it.

    Ok, so there are two URLs listed:
    https://staging.wgmarketingtest.com/checkout?wc-ajax=checkout
    https://staging.wgmarketingtest.com/checkout?wc-ajax=update_order_review

    The first one is where I see this error when I visit the URL and in the the HTML tab in Firebug. This URL has an HTML tab where the other has a JSON tab.

    Wow, you need to increase your memory limit. I’m surprised WP isn’t doing it for you. It’ll usually bump it to 64MB automatically. I’ve had no trouble running EWWW with a 32MB limit before, but when you add in any other plugins (and I suspect WP Commerce isn’t the most lightweight of plugins), you’re going to need more than 40MB.

    Excellent! Increased the memory limit to 256MB and everything is working now. I’m pretty new to WP so I really appreciate you helping me through this!
