Support » Plugin: W3 Total Cache » Using wp_cache_incr() in a plugin causes crash

  • I use caching in my plugin Simple Fields and to invalidate the cache I use the function wp_cache_incr() that is available since WordPress 3.3.

    W3 Total Cache gives this error after being installed:
    “Fatal error: Call to undefined function wp_cache_incr()”

    Support for wp_cache_incr would be great and will probably solve problems with other plugins in the future too.
