Most WordPress hosting solutions these days have a mix of plugins that they install into your WP stack to optimize performance on their platform. There’s absolutely nothing wrong with that, however it can create problems at the new host when you change providers.
Here’s a list of some items you should disable and/or remove depending on your old provider:
Gridpane
Regular plugins
- WP fail2ban (Litespeed WAF provides this functionality)
MU-plugins
- wp-cli-login-server.php (our Instant Login addon provides this functionality)
