I always make a local copy from production website, when providing technical assistance on various WP websites,.
Recently, I started using Local by Flywheel.
Just a couple of times, I stumbled in errors of the same kind, happening on production websites only at the same time I was working on the local copy, i.e.:
- mysqli_query(): MySQL server has gone away …
- Duplicate entry ‘0’ for key ‘PRIMARY’ …
I double checked wp-config.php to ensure it was not messing with a remote connection.
Also, I think that a remote Database wouldn’t accept any kind of request, if coming from a local, unauthenticated client.
Anyway, could a custom plugin or php template with a hard coded remote query make changes on the production copy, so creating issues right there? I would like to get rid of any doubt.
Thanks in advance!
