Memory error

WP version: 3.5
WP HTTPS version: 3.2.3

A new installation of WP HTTPS causes the admin panel to throw a fatal error regarding memory.

Screen output on the wp-admin page is:
PHP Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0

Trapped memory error is:
PHP Fatal error: Out of memory (allocated 57409536) (tried to allocate 5402328 bytes) in /home/hagstorn/public_html/wp-content/plugins/wordpress-https/lib/WordPressHTTPS/Module/Parser.php on line 234

Line 234 is:
$this->_html = str_replace($url, $updated, $this->_html);

I’ve jacked up php memory limit to 1024 and still get this error.

Is anyone else getting these errors??
