Text fopen(); gives 503 error

Hi all,

On my WordPress 2.2.1 blog I’m trying to post some PHP code examples on using files in PHP.

I am trying to post the text “fopen($filename, ‘a’);” but whenever I post this text or any other text like “fopen();” in a new post I get a 503 error saying:

Service Temporarily Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

I’m unsure as to why WordPress is trying to perform this fopen command even though I have it wrapped around a [php] [/php] code bracket (iG:Syntax Hiliter) and it should not parse any PHP code but rather display the code only.

If anyone has any ideas or solutions they would be much appreciated.

Thanks,
Alex.
