Is it possible to perform a conflict test? Having a staging site to check, would be even better. * Can you also inform me about the following? – previous Defender version (before v.2.2.7) – WP version – any other update that happened along with Defender * Thank you, Dimitris * Thread Starter [meichanjr](https://wordpress.org/support/users/meichanjr/) * (@meichanjr) * [6 years, 2 months ago](https://wordpress.org/support/topic/plugin-page-display-blank/#post-12632211) * Hi [@wpmudev-support6](https://wordpress.org/support/users/wpmudev-support6/) * Here are my env: – WordPress 5.4 – Defender Version 2.2.7 – Chrome Version 80.0.3987.149– Mac OS (Dark Mode) -> i just notice that may be it can be the case since error log say “Cannot read property ‘high_contrast’ of undefined”” * Before i updated to Defender Version 2.2.7, everything work fine. * Plugin Support [Imran – WPMU DEV Support](https://wordpress.org/support/users/wpmudev-support9/) * (@wpmudev-support9) * [6 years, 2 months ago](https://wordpress.org/support/topic/plugin-page-display-blank/#post-12649952) * Hello [@meichanjr](https://wordpress.org/support/users/meichanjr/) * I trust you are doing well! * Would you please run a test for a conflict with another plugin? To run this test, please deactivate all plugins besides the Defender and see if the blank screen is still there. * If all is well, please start activating one plugin at a time till the issue will be back. If the error still there please switch to a default WordPress theme. If it is still persisting, try re-installing the Defender plugin. * This way you will find with what plugin there is a conflict. * Please have a backup of your site before running this test. * Let us know how it went! * Kind regards, Nastia * Thread Starter [meichanjr](https://wordpress.org/support/users/meichanjr/) * (@meichanjr) * [6 years, 1 month ago](https://wordpress.org/support/topic/plugin-page-display-blank/#post-12660249) * This plugin enable user to config Accessibility, in the Setting page you can found option “Enable high contrast mode”. * And that’s all, there is no conflict with others plugins. * Plugin Support [Dimitris – WPMU DEV Support](https://wordpress.org/support/users/wpmudev-support6/) * (@wpmudev-support6) * [6 years, 1 month ago](https://wordpress.org/support/topic/plugin-page-display-blank/#post-12663226) * Hello there [@meichanjr](https://wordpress.org/support/users/meichanjr/) * This is true, we were still unable to replicate the aforementioned error that’s why we proposed a conflict test, as it can be another plugin/theme triggering it. * Were you able to fix this by toggling the high contrast option?
