You can deactivate and reactivate this plugin, it will try to load as the first plugin upon activation. * If this does not help you out deselect “Send headers when user is blocked”. This will no longer send headers but only display the block message. This however will mess up your website if you use caching software for your website. * Thread Starter [mehmeh](https://wordpress.org/support/users/mehmeh/) * (@mehmeh) * [10 years, 4 months ago](https://wordpress.org/support/topic/error-logs-blockcountry-checksphp/#post-6951107) * You mean it will mess up the website for blocked users or for everyone? * Plugin Author [Pascal](https://wordpress.org/support/users/iqpascal/) * (@iqpascal) * [10 years, 4 months ago](https://wordpress.org/support/topic/error-logs-blockcountry-checksphp/#post-6951110) * IF you use a caching solution permitted visitors may get blocked pages and blocked visitors may get the actual page. The caching solution needs the headers to function. * If you don’t use a caching solution nothing ‘bad’ happens. Not sending the headers is just not as clean as it should be.
