Wordfence: UNABLE TO UPDATE RULES

No rules were updated. Please verify you have permissions to write to the /w

管理页面横幅（关闭之后一刷新又出来了）显示：

The last rules update for the Wordfence Web Application Firewall was unsuccessful. The last successful update check was July 7,2020 5:06 pm,so this site may be missing new rules added since then. You may wait for the next automatic attempt at July 21,2020 5:07 pm or try to Manually Update by clicking the “Manually Refresh Rules” button below the Rules list.

手动升级时显示：

No rules were updated. Please verify your website can reach the Wordfence servers.

（疑似）解决方法：

通过跟支持人员的散装英语交流，某种程度上解决了问题。

设置php.ini

编辑/usr/local/php/etc/php.ini。修改以下参数：max_execution_time = 300memory_limit = 256M修改好后重启PHP（或者重启整个lnmp也行）。

删除wflogs文件夹

删除该文件夹，让Wordfence重新生成该文件夹。具体位置为：网站目录/wp-content/wflogs直接rm -rf干掉就行。然后刷新网页，就应该已经重新生成了。
