Problems clear cache

[Andros9]

I am trying to clean cache through admin and I get the following problem:

URI: index2.php?option=com_admin&task=tools&tname=clean_cache
 Path: includes/Core/filemanager.class.php
 Line: 928
 rmdir(/home/diafania/public_html/cache/static/mail/roundcube/) [function.rmdir]: Permission denied

What does it mean? Can someone assist?

Thank you,
Andreas

Check that the folder or directory permissions to cache is 755.

[Andros9]

Yes , folder has permissions set to 755. What else might be the problem?

[webgift]

cache and tmpr folders must have been set to 777.

[Andros9]

How about the folders inside cache that is static and simplepie? Are they set to 777 or 755. I have tried to set them to 777 since they are 755 now to see if that solves the problem but their ownership is set to "nobody" and I can not change their permissions.

Thank you,
Andreas

If the folders and files were created before the cache was set to 755, then you want to change the folders to 755 and the files to 644.

You can also use tools - > clean cache.
