Plugin breaks or causes issues when activated in WordPress multisite environments.
Plugin Is Not Compatible with Multisite
Key Points: Activating or using the plugin on a multisite causes errors, missing features, or unpredictable behavior.
Everything works great — until you activate network mode. Suddenly, plugin settings disappear or only apply to the main site. Multisite isn’t always well supported.
🚫 Common Pitfalls
- Settings saved globally instead of per site
- Plugin fails to hook properly into network admin
- Incorrect capability checks for super admins
🛠️ What to Try
- Check plugin documentation for multisite compatibility
- Only activate the plugin per site (not network-wide)
- Replace with a plugin designed for multisite installs
🧠 Dev Tip
If you’re coding your own plugin, test with is_multisite() and use switch_to_blog() where appropriate.
