I just moved my blog to a new server, and it turns out that now all the permalinks don’t work. It gives a 404 file not found error message.
I’ve tried to replace the .htaccess file with a fresh one, but nothing happened.
Simply USE a redirect plugin for get rid of 404 error.
All you have to do is installing a redirect plugin and put your old permalinks structure. Then all your links automatically redirect to new permalink structure without 404 error.
