Reason: First post was all contained in a small box, hard to read * Plugin Support [wfphil](https://wordpress.org/support/users/wfphil/) * (@wfphil) * [1 month, 1 week ago](https://wordpress.org/support/topic/connectivity-ntp-time-offset-issues/#post-18871169) * Hi [@vunderbar](https://wordpress.org/support/users/vunderbar/) * The connection error is likely due to the WP Ghost plugin and removing it should fix the error. Plugins like this that try to hide that a site is using WordPress can cause other plugins to malfunction including Wordfence. For example you may find the Wordfence scans won’t start or complete when using WP Ghost. * NTP is a protocol that allows for remote time synchronization if a server’s clock time is not correct. You can ask your hosting provider to check that for you. Wordfence **Login Security** uses this protocol to ensure that it has the most accurate time which is necessary for our TOTP based two-factor authentication feature to work correctly if you are going to use that. * It doesn’t matter what order you install plugins in WordPress. * We can only provide support for our plugin and general WordPress security advice so you can ask WooCommerce for advice on theme and page builder support for their plugin. * Thread Starter [Vunderbar](https://wordpress.org/support/users/vunderbar/) * (@vunderbar) * [1 month ago](https://wordpress.org/support/topic/connectivity-ntp-time-offset-issues/#post-18878059) * Hi Phil, * Sorry for the delayed reply. * According to WP Ghost, they say they’re compatible with Wordfence: “Note! WP Ghost works with all plugins who run in the admin area. Compatibility issues are unlikely, especially if you use the Safe Mode from WP Ghost.”And as noted on this page: “WP Ghost is compatible with the most popular plugins.” [https://wpghost.com/kb/wp-ghost-compatibility-plugins-list/ ](https://wpghost.com/kb/wp-ghost-compatibility-plugins-list/)( Security Plugins section) * They also claim it’s complementary / good when used together with WF: “WP Ghost is a hack-prevention security solution for your WordPress site. Together with the WordFence plugin, it will boost your website security by stopping hacker bot attacks, spammers, and viruses and preventing data loss.” [https://wpghost.com/kb/wp-ghost-and-wordfence-security/](https://wpghost.com/kb/wp-ghost-and-wordfence-security/) * The WF scans have been able to run and complete without issue. * That being said, removed WP Ghost, reran a WF scan, checked Diagnostics and … all is fine again. * Re/ the NTP issue, this has been resolved after working with the host provider. Re/ plugin install order, good to know.Re/ your note on page builders and WooComm, figured you might say that. Was just wondering if others who have used these together might have some tips or feedback from their experience. * Thanks Phil Viewing 3 replies - 1 through 3 (of 3 total) You must be [logged in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fconnectivity-ntp-time-offset-issues%2F%3Foutput_format%3Dmd&locale=en_US) to reply to this topic. *  * [Wordfence Security - Firewall, Malware Scan, and Login Security](https://wordpress.org/plugins/wordfence/) * [Frequently Asked Questions](https://wordpress.org/plugins/wordfence/#faq) * [Support Threads](https://wordpress.org/support/plugin/wordfence/) * [Active Topics](https://wordpress.org/support/plugin/wordfence/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/wordfence/unresolved/) * [Reviews](https://wordpress.org/support/plugin/wordfence/reviews/) * 3 replies * 2 participants * Last reply from: [Vunderbar](https://wordpress.org/support/users/vunderbar/) * Last activity: [1 month ago](https://wordpress.org/support/topic/connectivity-ntp-time-offset-issues/#post-18878059) * Status: resolved
