If you are getting load of this error after upgrading to Zend framework 1.10 and greater, you can fix it by changing Zend/Loader.php file
Change method isReadable() to following
Also make sure anything in your include path should be in your basedir option too.
Waring!!! use the code at your own risk as I have not done extensive tests.
/**
* Returns TRUE if the $filename is readable, or FALSE otherwise.
* This function uses the PHP include_path, where PHP's is_readable()
* does not.
*
* Note from ZF-2900:
* If you use custom error handler, please check whether return value
* from error_reporting() is zero or not.
* At mark of fopen() can not suppress warning if the handler is used.
*
* @param string $filename
* @return boolean
