He told me to remove file 403.shtml from my site directory. After I removed it (actually I just renamed it to another name), now I can view date archives without getting the 403 error page:
I don’t know why 403.shtml can caused the problem. At first, I thought it caused by wrong parameters in .htaccess file but it wasn’t it.
Anyway, I am happy my site is ok now. 😉 [tags]permalinks, permalinks structure[/tags]
