HTTP Error 412: Precondition Failed
412 errors in the HTTP cycle
Any client (e.g. your Web browser) goes through the following cycle:
* Obtain an IP address from the IP name of your site (your site URL without the leading 'http://'). This lookup (conversion of IP name to IP address) is provided by domain name servers (DNSs).
* Open an IP socket connection to that IP address.
* Write an HTTP data stream through that socket.
* Receive an HTTP data stream back from your Web server in response. This data stream contains status codes whose values are determined by the HTTP protocol. Parse this data stream for status codes and other useful information.
This error occurs in the final step above when the client receives an HTTP status code that it recognises as '412'.
That's a new one. It almost has to be an issue with your web host...but the funny thing is, you can still make normal posts with BBCode in them?
