stebcom on "[Plugin: WP Super Cache] Fatal error trying using dynamic content"

I forgot to replace

add_cacheaction( 'wpsc_cachedata_safety', 'dynamic_output_buffer_test_safety' );

with

add_cacheaction( 'wpsc_cachedata_safety', 'dynamic_cache_test_safety' );

but I'm not able to get things working: I simply don't see the code replacement.
