== Frequently Asked Questions ==

= Does Zero Spam for WordPress block user IPs? =

*Not by itself.* Zero Spam for WordPress does not block IP addresses by itself. Visitors that are getting blocked have either been manually blocked by the site admin or appear in one of the IP blacklist like [Stop Forum Spam](https://www.stopforumspam.com/), [Project Honeypot](https://www.projecthoneypot.org/), or the [Zero Spam IP database](https://www.zerospam.org).

If a legitimate user is getting blocked, check the Log (Admin > Dashboard > Zero Spam > Log) to get further details why they were blocked. You can adjust how strict the 3rd-party blacklist checks are or disable those if you find that your users are prone to being flagged as spam/malicious.

= Does Zero Spam for WordPress check Jetpack comments? =

**No.** Zero Spam for WordPress is unable to integrate Jetpack. For more information, see [https://wordpress.org/support/topic/incompatible-with-jetpack-comments](https://wordpress.org/support/topic/incompatible-with-jetpack-comments).

= How do I boost performance of Zero Spam for WordPress? =

**Enabled caching.** Caching is highly recommended and will prevent repeated calls to third-party API and access checks on each page visit.

You can also adjust the cache and API timeout settings in admin depending on your server and specific needs.

= What Zero Spam for WordPress WP-CLI commands are available? =

* `wp zerospam autoconfigure` — Auto-configures with recommended settings.
* `wp zerospam settings` — Displays all plugin settings.
* `wp zerospam set --[SETTING_KEY]=[VALUE]` — Updates a plugin setting.

= Are you getting a `ftp_fget` PHP warning? =

Some hosts have issues with they way they access files. If you're seeing a `ftp_fget` PHP notice, setting the `FS_METHOD` constant to `direct` in `wp-config.php` above the line `/* That's all, stop editing! Happy Pressing. */` should solve the problem:

`define('FS_METHOD', 'direct');`

If hosting with Pantheon, see their [known issues page](https://pantheon.io/docs/plugins-known-issues#define-fs_method) for more information and what to do to resolve it with their `$_ENV['PANTHEON_ENVIRONMENT']` variable check.
