Hi Phil:

Yes wpmathpub works just fine on wordpress 3.2.1 I use it on my other website with wordpress 3.2.1 without any problem: http://www.lecturemaker.com

The warning message seems pretty clear, your web host does not allow you to usethe chmod function. The function is used in wpmathpub.php to automatically make one sub-directory called “./img” available for both read and write operations. In this way, new math graphics images can be created to replace the math text during the math publishing process in your blog posts.

This issues with chmod has come up to my attention from would-be users a few times. So there is a simple but manual fix already baked into the php code. Change the line listed below in your copy of the php code from “true” to “false” so that “AUTOCHMOD” is defined as “false”. Then have your administrator make the subdirectory “./img” be writeable and readable. If security is very restricted, then your admin may have to create this sub-directory as well. Have him/her read the php code comments to see where this directory should be located.

//
// Control automatic test and set feature for write access to ‘img’ directory.
// Automatic test and set feature when define(“AUTOCHMOD”, true);
// Manual automatic test and set feature when define(“AUTOCHMOD”, false);
define(“AUTOCHMOD”, true);

Hi Sascha:

To learn how to use wpmathpub, you can look at the help file offered by the math font engine provider: http://www.xm1math.net/phpmathpublisher/doc/help.html

I used “invisible parenthesis” to group the “-” sign with the “x” in the exponent like this:
[ pmath ]f(x)=e^{-x}[ /pmath ] only without the spaces in the pmath tags.
