I am using quickcache and really like the plugin. There's one thing, I do not know. As I am using a splashscreen on my page with the plugin wp splashscreen I want to exclude this page from caching. So I am no developer or good programmer and I am not sure where to put this code:
- Code: Select all
define("DONOTCACHEPAGE", true)
does someone know the plugin and can help me to integrate that line of code?
this is the plugin:
- Code: Select all
