 * Hi,
 * I was on another forum related to wordpress.org speed issues observed lately 
   and among other things, I was pointed to look for any plugins which uses `session_start()`
 * I can see that your plugin uses this on Line 239 in `woo-order-export-lite\classes\
   formats\abstract-class-woe-formatter-plain-format.php`
 * The post which mentions this is here:
    [https://wordpress.org/support/topic/wordpress-org-servers-slow-plugin-updates-timing-out/#post-12707878](https://wordpress.org/support/topic/wordpress-org-servers-slow-plugin-updates-timing-out/#post-12707878)
 * > One thing you might check, if you have any code anywhere in your themes or 
   > plugins or anything else which calls session_start(). This is a known problem,
   > if a plugin or theme is incorrectly always attempting to start the PHP sessions
   > functionality, then that can cause a blocking condition. The solution is to
   > remove the plugin or theme or to have it not call session_start().
 * Please review and guide me
 * Thanks

 * Hello
 * This code works only during export and only if you use Summary mode (by products
   or by customers).
    So it shouldn’t affect to update. You can deactivate our plugin.
 * But probably, your internet provider blocks outgoing connections ?
