Bug Fix manually delete caching method
According to documentation, to manually delete cache for page "/foo/bar" we should run $this->output->delete_cache('/foo/bar'), but in this case MD5 hash will be calculated for "http://site.com//foo/bar" and this is why, we should pass $uri without beginning slash (ie, "foo/bar"). But the problem is that there is no way to delete cache for home page because:
1) $this->output->delete_cache('/') — MD5 hash will be calculated for "http://site.com//" and cache file will not be deleted.
2) $this->output->delete_cache('') — MD5 hash will be calculated for "http://site.com/%CURRENT_PAGE%" and again, cache file will not be deleted.
Trimming the beginning slash, we enable ability to delete cache for home page by calling $this->output->delete_cache('/'). Also, this method will work as specified in the documentation.1 file changed
