Joomla cache handler only shows memcached

Question

My cache handler in Joomla! only shows 'memcached (experimental)', and not File etc. I was able to change the cache handler in my configuration.php but I'd still like to know why File is not shown as a cache handler option? How can I fix it? I checked folder rights already.

Thank you

First of all you should check the administrator/cache and /cache folders exist. Obviously file cache can't work without those folders. If they don't exist just create them and that may solve the problem. If the problem is still not solved then perhaps the below has happened.

This occurred to me when I transferred my site to a new location. When I investigated the configuration.php file at the bottom of the file

public $cache_path = '/home/xxxxxx/cache';

Was incorrect and had the old location. This was causing Joomla! to say:

Failed to load 'XXXXX' template: Joomla cache path does not exist! and in the back end cache path does not exist. I also could not see the file option in the global configuration. I also could not save the global configuration.

Editing my configuration.php file manually resolved this issue for me.

And now you can also see the path to cache folder and edit it (bit late of course). I've submitted an issue to Joomla! as I think these fields should not disappear.

Answer 2

Create a folder called "Cache" to the root of your website (or to the directory where you have installed Joomla) and apply 755 permission to it. Then disable cache plugin, and you should be able to select "File" as Cache handler.

Hope it helps

PS: To remove "memcached" you can delete all the lines including "memcached" from your configuration.php file (remember to set 644 and when you finish editing back to 444)

Check that /administrator/cache and /cache folders exist and that your web servers has write permisions for it. You can check this in System->System Information->Folder Permissions tab - everything here should be green.
