Title: jQuery Error Last modified: December 22, 2020 --- # jQuery Error * Resolved [konstantindbm](https://wordpress.org/support/users/konstantindbm/) * (@konstantindbm) * [5 years, 4 months ago](https://wordpress.org/support/topic/jquery-error-87/) * Hi, * So at the moment I’ve disabled the plugin on the website, but basically, we were experiencing an issue where the plugin doesn’t function correctly on the product single page. * What would happen is that I would click on a size option (e.g. Medium) and it will select the option correctly, however if I select another option it will not show that option as selected. * We also get a Javascript Error every time a variation option is selected: * Uncaught TypeError: _.contains is not a function * This error is shown within the frontend-min.js file of this plugin. * Looks like depreciated jQuery but I’m not sure. * Do let me know if you need any additional information. * We’re running latest version of WordPress with Astra theme and Elementor. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fjquery-error-87%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 7 replies - 1 through 7 (of 7 total) * [pluginswoo](https://wordpress.org/support/users/pluginswoo/) * (@pluginswoo) * [5 years, 4 months ago](https://wordpress.org/support/topic/jquery-error-87/#post-13832158) * [@konstantindbm](https://wordpress.org/support/users/konstantindbm/) * Could you please record your issue using a tool like uesloom.com? and is it working without our plugin? * Thank You * Thread Starter [konstantindbm](https://wordpress.org/support/users/konstantindbm/) * (@konstantindbm) * [5 years, 4 months ago](https://wordpress.org/support/topic/jquery-error-87/#post-13861081) * Hi, Thank you for your reply. * As you can see in the video below, there is a jQuery issue that links directly to this plugin. Furthermore, you can see that on the front end, when I select an option it gets marked as not in stock when it is clearly in stock. * [https://www.loom.com/share/e7b8c483ab0f4b39bb30992c1bc7016f](https://www.loom.com/share/e7b8c483ab0f4b39bb30992c1bc7016f) Many thanks! * Thread Starter [konstantindbm](https://wordpress.org/support/users/konstantindbm/) * (@konstantindbm) * [5 years, 4 months ago](https://wordpress.org/support/topic/jquery-error-87/#post-13890624) * Hi, * Any new updates?

Please kindly do a plugin compatibility check by doing these steps to identify the error : * => Deactivate all of your additional plugins except WooCommerce and WooCommerce Variation Swatches Plugin. * => See if the problem persists. If the problem resolved, you can tell which plugin might be the culprit of this error by activating your additional plugins one by one. * Looking forward to hearing from you soon. * Thank you * Thread Starter [konstantindbm](https://wordpress.org/support/users/konstantindbm/) * (@konstantindbm) * [5 years, 2 months ago](https://wordpress.org/support/topic/jquery-error-87/#post-14058758) * Hi again, * As mentioned in my previous reply, I have tested it with and without all plugins enabled, to no avail. * I tested it again today, with everything up to date, and with just it and Woocommerce enabled, no difference.
