I have been searching and reading all evening on enabling a front end cache and a back end cache. According to this: http://xenforo.com/help/cache/ I just need to add the lines of code which I have. But one little part confuses me. Should I also add this line? Code: $config['cache']['cacheSessions'] = true; I added these: Code: $config['cache']['enabled'] = true; $config['cache']['frontend'] = 'Core'; $config['cache']['frontendOptions']['cache_id_prefix'] = 'xf_'; $config['cache']['cacheSessions'] = true; Now according to this thread @Jake Bunce said it should be written to "cache_dir" under your tmp directory. But After enabling it this afternoon I am still not seeing any data or folder being created or written to. Is this because I didn't add the line of code listed above? Any help would be appreciated. I just want to make sure its working.
