Wordpress cache

In the process of using WordPress to build a website, many "detours" have been taken in optimizing WordPress performance and speeding up website access. When the website access is slow and the CPU memory is exhausted, the first thing I think of is upgrading the server configuration. Later, I find that some unscrupulous VPS merchants severely restrict resources behind the scenes, and it is really hurtful to pay more to upgrade.

Today I received a message from a friend on WeChat, reminding me that the blog cannot be opened. Sure enough, after opening it, it directly displayed "Your site has encountered a fatal error." If you think about it carefully, in addition to being attacked recently, the blog has installed the W3 Total Cache plug-in. According to speculation, it can basically be concluded that the plug-in is to blame. .
