Title: Blank screen Last modified: August 31, 2016 --- # Blank screen * [wPcoMuser](https://wordpress.org/support/users/wpcomuser/) * (@wpcomuser) * [10 years, 3 months ago](https://wordpress.org/support/topic/blank-screen-63/) * I got on one website, without changing anything, all pages resulting simply “ error”. I traced the error to the iThemes Security plugin, but could not debug the error. I removed all advanced options, but still the error persisted. Disabling the plugin fixed things. * Then, on a separate install of WP, I got all pages resulting a blank screen. Again, could not debug the issue. Disabling iThemes Security fixed the issue. * I cannot trace this error, but on two installs the chances this is not caused by this plugin are pretty small. Any thoughts? * [https://wordpress.org/plugins/better-wp-security/](https://wordpress.org/plugins/better-wp-security/) Viewing 7 replies - 1 through 7 (of 7 total) * [dwinden](https://wordpress.org/support/users/dwinden/) * (@dwinden) * [10 years, 3 months ago](https://wordpress.org/support/topic/blank-screen-63/#post-7008001) * [@wpcomuser](https://wordpress.org/support/users/wpcomuser/) * Let’s deal with the all pages showing ‘error’ issue in this topic. Please open a seperate topic for the blank page issue. * When the iTSec plugin triggers a host lockout, the ‘error’ page is displayed. Host lockouts are caused by too many invalid login attemps from a brute force attack OR by too many 404 requests. **Brute Force Protection** and **404 Detection** are the plugin features controlling this behavior. * So basically this is the iTSec plugin doing its work. * dwinden * Thread Starter [wPcoMuser](https://wordpress.org/support/users/wpcomuser/) * (@wpcomuser) * [10 years, 3 months ago](https://wordpress.org/support/topic/blank-screen-63/#post-7008035) * Well then it overwrote my whitelist of my own IP. And yes, I’m on a static. * [dwinden](https://wordpress.org/support/users/dwinden/) * (@dwinden) * [10 years, 3 months ago](https://wordpress.org/support/topic/blank-screen-63/#post-7008040) * [@wpcomuser](https://wordpress.org/support/users/wpcomuser/) * Did you whitelist your IP address temporarily (24h) or permanently ? * temporarily = iTSec plugin Dashboard/Settings/Logs page -> **Temporarily Whitelist my IP** button permanently = iTSec plugin Settings page -> Global Settings - > Lockout White List -> **Add my current IP to Whitelist** button * So if I understand correctly it has been working fine for a while and suddenly without any obvious change this issue started. Are you using the latest iTSec plugin release (5.2.0) ? * If so you must have updated the iTSec plugin recently since 5.2.0 was released 2 weeks ago. Any chance the issue started after updating the plugin to 5.2.0 ? * Are you able to access the site (frontend\backend) from a different IP ? * dwinden * Thread Starter [wPcoMuser](https://wordpress.org/support/users/wpcomuser/) * (@wpcomuser) * [10 years, 3 months ago](https://wordpress.org/support/topic/blank-screen-63/#post-7008074) * The only issues I experienced were since the update, but I do not know if they started immediately after updating or not. * Yes, I had long ago whitelisted my IPs permanently, and also when I log-in and change settings I generally also temporarily whitelist my IP (although unnecessary no doubt). * I tried uninstalling and reinstalling the plugin, same issue. * I also dropped all three “itsec” tables, and then reinstalled, and same issue. * I gave up before going through the options table to remove all options there. * I had the same issue from my home and my work IP. Did not try from my phone ( to give a third IP). When I get a moment I’ll reinstall, re-enable, and test that. * [dwinden](https://wordpress.org/support/users/dwinden/) * (@dwinden) * [10 years, 3 months ago](https://wordpress.org/support/topic/blank-screen-63/#post-7008103) * [@wpcomuser](https://wordpress.org/support/users/wpcomuser/) * It could be the host lockouts are occurring because of too many 404 requests. * Did you enable the **404 Detection** feature ? If so please check the Logs page and select 404 Errors as the Select Filter:. * If there are many 404 Errors logged you could temporarily try and disable the 404 Detection feature. Just too see whether is has any impact on this issue. * dwinden * Thread Starter [wPcoMuser](https://wordpress.org/support/users/wpcomuser/) * (@wpcomuser) * [10 years, 3 months ago](https://wordpress.org/support/topic/blank-screen-63/#post-7008194) * I will try, but this is on a site I can not take down for testing easily. I can more easily test the “blank screen” issue in the other thread. * [dwinden](https://wordpress.org/support/users/dwinden/) * (@dwinden) * [10 years, 3 months ago](https://wordpress.org/support/topic/blank-screen-63/#post-7008196) * [@wpcomuser](https://wordpress.org/support/users/wpcomuser/) * Can you post the website URL so I can have a look at it ? (I do realize that the iTSec plugin is probably deactivated). * It would help a lot if you could log into phpMyAdmin and export the content of the 3 wp_itsec_* tables and then provide us with that export file. This would help in analyzing the exact cause for the host lockouts. * Please note that even though I’m not an iThemes employee your data is safe with me. * dwinden Viewing 7 replies - 1 through 7 (of 7 total) The topic ‘Blank screen’ is closed to new replies. * ![](https://ps.w.org/better-wp-security/assets/icon.svg?rev=3529351) * [Kadence Security – Password, Two Factor Authentication, and Brute Force Protection](https://wordpress.org/plugins/better-wp-security/) * [Frequently Asked Questions](https://wordpress.org/plugins/better-wp-security/#faq) * [Support Threads](https://wordpress.org/support/plugin/better-wp-security/) * [Active Topics](https://wordpress.org/support/plugin/better-wp-security/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/better-wp-security/unresolved/) * [Reviews](https://wordpress.org/support/plugin/better-wp-security/reviews/) * 7 replies * 2 participants * Last reply from: [dwinden](https://wordpress.org/support/users/dwinden/) * Last activity: [10 years, 3 months ago](https://wordpress.org/support/topic/blank-screen-63/#post-7008196) * Status: not resolved
