Syntax Error

Hello,

In the screenshot you attached me I cannot see if the issue is related to YITH WooCommerce Wishlist.

I suggest you to try to deactivate all plugins, leaving only WooCommerce and YITH WooCommerce Wishlist active, and see if the problem is solved. If so, try to activate them again, one by one, to see which one causes the issue.
If the problem isn’t caused by a plugin, try to activate the default theme Twenty Sixteen and see if you have the same issue.
Also, if you have customized some files in your theme, please try with a fresh installation without any customization.

Please try this solution and let us know what issue shows.

Maybe the issue is due to other plugin or the theme.

I’m looking forward your response.

Have a good day.
