When I clear System cache from Joomla admin I am getting following error:
JCacheStorageFile::_deleteFolder Failed deleting 8887bfcb051ecf67459f16a8f1ce8af3-cache-com_jfbconnect-2c513f7b99f91f352921f8c0797ddd88.php
Only some cache group(s) have been cleared.
Error clearing cache group(s): Administrator > com_jfbconnect.
Please let me know the reason behined this and how to resolve this issue
Please check whether your /cache folder is unwriteable. Go into your Joomla backend and navigate to System > System Information > Folder Permissions. You should see a list of folders with whether they're writeable or not. If it is marked as unwriteable, then change the permissions and try again.
Can you change the cache folder permissions to 777 (from FTP/CPanel/etc). The normal cause of this warning is limited permissions on the folder. Once you've changed them, logout of backend and log in again before trying to clear the cache again.
