Issue with time out trashing posts

Currently Max_php_execution time is set to 500 sec (8.33 mins). It is not recommended to increase more.
After checking the log file we found that "Autoblog" plugin is causing this issue and its taking more time to delete the trash posts.

Following error code:

2015/03/19 16:42:31 [error] 4192#0: *413089 FastCGI sent in stderr: "PHP message: PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, class 'SSLInsecureContentFixer' does not have a method 'adminMenu' in /var/www/example.com/htdocs/wp-includes/plugin.php on line 496PHP message: PHP Stack traceHP message: PHP 1. {main}() /var/www/example.com/htdocs/wp-admin/edit.php:0PHP message: PHP 2. require_once() /var/www/example.com/htdocs/wp-admin/edit.php:10PHP message: PHP 3. require() /var/www/example.com/htdocs/wp-admin/admin.php:115PHP message: PHP 4. require_once() /var/www/example.com/htdocs/wp-admin/menu.php:269PHP message: PHP 5. do_action() /var/www/example.com/htdocs/wp-admin/includes/menu.php:149PHP message: PHP 6. call_user_func_array:{/var/www/example.com/htdocs/wp-includes/plugin.php:496}() /var/www/example.com/htdocs/wp-includes/plugin.php:496" while reading response header from upstream, client: 123.201.118.6, server: example.com, request: "GET /wp-admin/edit.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "example.com", referrer: "https://example.com/wp-admin/edit.php?s=&post_status=trash&post_type=post"
