Have searched the archives and no solution. My WP 1.5 installation has been working fine. Last night, I posted an entry and afterwards I get nothing (web site not available) when I View Site or enter the URL, with or without index.php added. I cleared the browser cache and it does this on three computers. WP-admin works fine, including post views, etc, but no access to the public. I do not have an index.htm(l) page anywhere. I am using the Semlogic theme, but I changed it and problem was still there. The database is fine. I am going nuts. Can anyone help? thanks.
