Apache2 under Ubuntu 12.04
I get a 403 error only sometimes when a URL is passed to a PHP script in WordPress via the PressThis button. e.g.
This results in a 403 in the browser, and access.log is appended. But error.log is not appended.
Other URLs don't fail - they work properly, such as
"GET /wp-admin/press-this.php?u=http%3A%2F%2Fwww.yeehaw.com%2Fproducts%2Fduet2.php&t=Apogee%20Duet%202%20-%202%20IN%20x%204%20OUT%20USB%20audio%20interface&s=&v=4 HTTP/1.1" 200 7962 "http://www.apogeedigital.com/products/duet2.php" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.52 Safari/537.17"
I have set
loglevel to the most verbose setting of
emerg. No error appears when the 403 is thrown.
Also, I have edited
.htaccess to a minimal version that does no security and the condition still persists for some URLs.
