# Getting “Unknown error: E_HTA_R” when making changes to settings

 * I have the LiteSpeed Cache plugin set up on my site, but it’s not working. I 
   always get “x-litespeed-cache: miss” when viewing the website while logged out.
 * So I’ve been trying to fiddle with settings to see if there’s something set wrong,
   but every time I make a change to the settings I get an error saying “Unknown
   error: E_HTA_R”, while simultaneously getting a message confirming “Options saved”
 * Just curious what this error means? I can’t find anything on google about it.
 * Thanks in advance!

 * when you save , the plugin will attempt to write its rules into .htaccess , the
   error you got , seems to be the .htaccess file is NOT writable , please check

 * Thanks for the response! I think this particular problem came from my following
   instructions in a Litespeed article which told me to add the following to my 
   wp-config:
 *     ```wp-block-code
       define("LITESPEED_CFG_HTACCESS", "/wordpress/.htaccess");
       ```
   
 * I added this because it was presented as a possible solution to the caching not
   working. I have wordpress installed in a subdirectory.
 * I tried changing the path used in that snippet and the error went away, so perhaps
   I just used the wrong path.
 * However, the ache still isn’t working. So I’m at a loss. Perhaps I should make
   a new thread for this, as it’s a bigger issue.
 * Is there something else I need to do in order to get the caching working for 
   a wordpress install in a subdirectory?
 * Thanks in advance!

   path

 * you should set it like this , replace `xxx` to your actual user

 * Thanks for the response! I’ve added that, but still getting “miss” from litespeed.
 * I tried disabling litespeed through cpanel and enabling it again, and I also 
   deleted and reinstalled the litespeed plugin. Still nothing.
 * Is there something else I should be checking? I’ve looked up different troubleshooting
   methods and I can’t see any reason this isn’t working.

 * please confirm that you have properly replace the xxx in my code ?
 * also once you added the define , go to plugin’s setting page , any page , click
   save , so it will trigger the htaccess write again
 * once it is saved, manually verify the both .htaccess, see if you can find the
   cache related rules , you can see them wrapped by something like `#LSCACHE .....`

 * I did properly replace the xxx in your example, and I’ve confirmed that the .
   htaccess in the /wordpress/ directory and the /wordpress/wp-content/ directory
   both have LScache content.
