This option turn on the Gzip compression of our css and js files. They will be called in with .php file extension names in your website's source.
This is how often the cache will be automatically refresh itself. To not to let it automatically refresh, you should use the word: static
The "static" keyword is the best option, because if you give a number, that can generate a lot of cache files, and fill up your server. If you have a lot of cache files, you can delete them, just click on Refresh Slider to make your sliders have cache files.
This is where your cache files will be stored.
This option turns on the language file's debugging, so it will show, which words were translated and which weren't. It could help to improve the translation.
Log possible problems
Mostly this option will only log, if you are missing the wp_head or wp_footer functions from your theme. But sometimes it also writes the error message into our backend, even if you don't have it, because not all of your pages need those functions. If you don't have that error in your theme, and it bothers you, that it always pops up, then just turn this option off.
