Today when I opened my blog , I found that if I click any links on the sidebar, it can't work. Can you tell me what's wrong with it? This is my blog: http://www.shopwo.com/ Please help me ! Thank you very much!
the links to the other sites work....its just your internal links do not....what have you changed recently?
Check whether you did any changes in permalinks of pages in your portal. The URL for each page may be changed or updated. Try to open these pages from your admin panel.
It appears you have a problem with .htaccess file. Somehow re-write rules defined there to enable Permalink are no longer working. Try to go to Admin->Settings-Permalinks - verify that permalink is properly defined and Update Options. If you host is properly configured - you .htaccess will be recreated and all links will begin to work - otherwise you will need to crate .htaccess file manually in the root folder of your blog. Some guidelines on htaccess can be found here: http://codex.wordpress.org/Using_Permalinks
