After launching a blog for 2 month with smooth operation til yesterday all links have been broken (404 page)except I can only go directly to the homepage(without permalink details)
I changed the permalink format to the default and it works but cannot access through search engines as the old permalinks have been stored in google cache hence no traffic from search engines at the moment.(i need to use the custom permalink).
I have customized the permalinks to /%category%/%postname%/ format for 2 months without any problem but now my blog is dead.
How can I address this problem?
Thanks in advance
