Figured it out. Simple SEO module had an echo statement I had to remove. Not sure why it wasn't an issue before.
includes/init_includes/init_ssu.php:
PHP Code:
function _set_name($sql_query, $cache, $identifier, $id){
$result = $this->_get_name_from_db($sql_query, $cache);
$result = $this->_parse_name($result).$identifier.$id;
$file_name = $this->{"build_$cache"}($id);
//echo $file_name;
// write to file EVEN if we get an empty content, that just means the productname is blank
$this->_write_to_file($this->cache_path[$cache].$file_name, $result);
return $result;
}
I commented out echo $file_name; above and it fixed it.
