Hi Patrick,
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 the WooCommerce and Additional Variation Images Gallery Plugin.
=> See if the problem persists. If the problem is 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
