Thanks Ed. They have done the updates and upgrade on the server. Seems better now.
Just one thing. I found there are contents/nodes which I inserted earlier is not listed in the content list at the backend. However, it displayed in View page (but linked to page not found)and yet, records exists in the database (node table).
So I think something wrong with the data in the database already. Just wondering how to fix this? Is there a module that can repair the database without accessing it? Cos I cannot access to the CP and database, so I need a tool to do this. I am currently using backup and restore module to extract the database, restore in my localhost and do the checking. Please advise if you know. Thanks!
