rustumT	Background of the issue: I was trying to update a post in the backend of my WordPress site. This issue occurs when I save any WooCommerce product that is not in the primary language. The problem started after updating to version 4.7.6. The issue can be seen at this URL: hidden link. Symptoms: I encountered an error message: 'Illegal offset type in isset or empty' in /public_html/wp-content/plugins/sitepress-multilingual-cms/classes/core-abstract-classes/class-wpml-element-translation.php on line 282. Instead of seeing 'Product updated', I got an 'Uncaught Error'. Questions: Why am I getting an 'Illegal offset type' error when saving a WooCommerce product? How can I resolve the error to successfully update products in non-primary languages?

rustumT	Hi there. After doing a plugin conflict test. I found the issue is from this plugin: WooCommerce Multilingual & Multicurrency Version 5.5.0. Kindly advise the next steps and how this can be fixed, even if it's just a temporary fix/patch for now. Thanks.

Could you please share the wp-content and database backup of your site? You can zip these files and send them to me using a file-sharing platform like Google Drive. That way, I can take a look and see what’s going on. Enabled the private reply for you. Thanks

rustumT	Hi, I just updated from v5.5.0 to 5.5.1 which was released today and I can confirm the issue seems to now be resolved. I saved a product in a secondary language and it saved as normal without the error. I believe we can mark this as resolved for now. Thank You.
