Cornerstone _cs_generated_styles Error Duplicate entry '0' for key 'PRIMARY' INSERT INTO `wp_postmeta`

With Cornerstone try insert a cache row in wp_postmeta table in Wordpress shows this error

Error Duplicate entry ‘0’ for key ‘PRIMARY’ on WordPress databe for INSERT INTO pc_postmeta (post_id, meta_key, meta_value)…

Cornerstone failed to insert for Autoincrement ID and then, for any reason, delete the private key and insert with ID 0.

Can you help me to solve this issue?

Hey @garcosc,

Thanks for writing in. I’m sorry though I’m currently not sure how to replicate this case. Would you mind providing the exact steps for us to arrive to the error? If you can record your screen, that would be great.

If you want the details to be private, you can post it in a Secure Note.
