Not sure, but, what version WordPress?
I read that RunPHP may not be compatible with WP2
WordPress 2.0.2
I have downloaded it from here http://dev.wp-plugins.org/wiki/RunPHP it’s write that it’s compatible with WP2
I use RunPHP with WP2.02 and I’m not having any problems.
I have problems from time to time. Sometimes I have to delete the page in question and recreate it with the PHP code then it works. Seems to be a hit or miss thing.
I read this on here:
http://codex.wordpress.org/User:Matt/2.0_Plugin_Compatibility
“# Of all PHP execution plugins only Exec-PHP (http://soeren-weber.net/post/2005/08/18/50/) and WP-Exec (http://www.navidazimi.com/projects/wp-exec/) seems to work. With RunPHP (http://svn.wp-plugins.org/runphp/) & PHP Exec (http://priyadi.net/archives/2005/03/02/wordpress-php-exec-plugin/) the processing when posts/pages are added seems to sanitize the current methods used by these plugins. If you’d prefer using RunPHP (and possibly PHP Exec) anyway, turn off “Users should use the visual rich editor by default” in Options –> Writing. “
I hope this helps.
I have the problem after i try to modify the post, the first time work…the other no
