Hi Ankit,
Thank you for reaching out to us. Please kindly do a plugin compatibility check by doing these steps to identify the error :
=> Deactivate all of your additional plugins except WooCommerce and Additional Variation Image Gallery for WooCommerce Plugin.
=> See if the problem persists. If the issue is resolved, you can tell which plugin might be the culprit of this error by activating your additional plugins one by one.
If the plugin conflict check doesn’t help, please record me reproducing your issue using a tool like this? https://www.useloom.com
It helps me to figure out the issue quickly and squash it immediately.
And don’t forget to add your site login details in the site login details area. I’ll check what’s happening there.
You can add new users by going to Users > Add New set the user and password for us, set the role to admin, and set the info here.
And add your site URL, login username, and password in the site login area. Follow this guideline: https://www.useloom.com/share/27c1f2ac633c4060b2da883d946107d7
Hope to hear from you soon!
Thank you
Plugin breaking variation selection
Ankit Purohit
The plugin is breaking variation products, tested it on 3-4 different instances that whenever the plugin is left active, user can no longer select variations or add them to cart (if 1 of the variation is default, that can be selected and added, non default one cannot be added).
