asked Nov 8 in Q2A Core by Gurjyot Singh
I tried to enable cache in admin section but it says that Cache director is not found? Actually, it's not written anywhere that a cache directory is needed to activate cache and exactly where the directory should be placed? Moreover, what "cache" be the exact name of the directory?

I don't have q2a version 1.8 but Did you look at this: https://github.com/q2a/question2answer/blob/dev/qa-config-example.php#L89 ?

fara mentioned steps are correct. I enabled cache on http://meta.question2answer.info site, you can test for speed. so far no issues seen.

To enable caching, the following steps need to be taken:

  1. Make a folder to store the cache files and chmod it to 777. Note: for security reasons the folder must be outside your document root. In other words you must not be able to view cache files in your browser like example.com/cache/123abc456def
  2. Set the QA_CACHE_DIRECTORY constant in qa-config.php to the location you made above (see qa-config-example.php for an explanation).
  3. Go to Admin > Caching and tick "Enable caching".
  4. Caching driver-> filesystem

I tried to do it as mentioned in qa-config file but it's still not working for me. I am getting "The directory /public_html/qa-cache defined as QA_CACHE_DIRECTORY is not writable by the web server." again and again. Although I have checked that the directory has 755 permission.

Can you please tell that how you made it work? Secondly, what is a caching driver and which one did you choose?

Hello @ProThoughts, I tried exactly what you said. But it's still saying that "The directory /qa-cache/ defined as QA_CACHE_DIRECTORY is not writable by the web server.". Although the directory is having 777 permission and still I am getting this error.

May below line is still in commented section/* */.  make sure to put below line output side comment section. can you check this again.

define('QA_CACHE_DIRECTORY', '/path/to/writable_cache_directory/');

    If you wish to use caching, you must define QA_CACHE_DIRECTORY to store the cache files. The
    directory must be writable by the web server. It also must be OUTSIDE the public root. For
    example if your site resides in '/var/www/yoursite/public_html', then the cache directory could
    be '/var/www/yoursite/qa-cache', but it cannot be '/var/www/yoursite/public_html/qa-cache'.


define('QA_CACHE_DIRECTORY', '/path/to/writable_cache_directory/');

I have written that line outside the comment and also defined the right path. If it wouldn't be outside comment then I would be getting an error like "No directory defined" or something like that.
