Regenerating Shop Thumbnails Not Working

Hi @forgetme

Typically issues like this are caused by a theme or plugin conflict. Try switching back to a default theme like Twenty Twenty-One and disabling all plugins except for WooCommerce to see if this resolves the problem.

If this fixes the issue, then re-enable each plugin one at a time, then the theme, until you find the one that’s causing the conflict.

Here is a link that better outlines that process:
