Index process is working now. Please try run this process later in Magento
Sometimes you’ll find in Magento that your indexes won’t run and will either be sat in the state of ‘Processing Now’ in Magento or when you try to reindex them, you get the error
[Index Name] process is working now. Please try again later.
If you come across this, then make sure the locks in your /var
directory are writeable (CHMOD 777).
/var/locks/*
You should find then, that you will be able to reindex in Magento successfully.
