 * Hi,
    I get this warning: 2020/01/03 06:32:47 [error] 22102#22102: *493387 FastCGI
   sent in stderr: “PHP message: PHP Warning: ./cache is not writeable. Make sure
   you’ve set the correct relative or absolute path, and that the location is server-
   writable. in /plugins/wp-rss-retriever/inc/lib/simplepie/library/SimplePie.php
   on line 1469” What can I do? Thanks and kind regards Martin

 * Hello,
 * This looks like it may be a file permissions on your server. Here is a quick 
   tutorial on how to change file permissions: [https://www.wpbeginner.com/beginners-guide/how-to-fix-file-and-folder-permissions-error-in-wordpress/](https://www.wpbeginner.com/beginners-guide/how-to-fix-file-and-folder-permissions-error-in-wordpress/)
 * Let me know if this works for you!

 * Hi,
    I checked the directory wp-content/cache : the permission is 755 like it
   should be. Any other idea? Thanks and regards Martin

 * Where should be the location of the directory for the caching?
    I saw, that all
   the settings are in SimplePie.php . And I do not want to modify your File. So
   it is easiest to create a directory “cache” at the right place, but where exactly?
   Thanks a lot!
