Why do my new INI/tpl files not take effect? Why does my new folder/article/other content object not appear on my site? Why is my content object still there even though I deleted it?

This could be a cache problem. Try deleting var/cache and reload the page. You generally should keep cache off while developing.

But some caches is always enabled, so can not be set in INI files, including image cache, ini file cache, template override cache, expiry cache. Although all of them can be updated automaticlly when corresponding sources are changed, sometimes the mechenism may not work. The only solution is to clear the cache.

A handy utility is shipped with eZ, clearcache.sh, which can be found under bin/shell/. Let's see its help information, and you can understand how to use it:

$ bin/shell/clearcache.sh -h
