is it efficient to download a full work template to my computer and work on it and then reupload it? thanks.

Hi raz buchnik,

if your changes reflect the content of the site, like the content inside a portfolio page, you can install some plugin for the "maintenance mode" to edit the content. Otherwise if you have to change some code, perhaps for some custom-post pages, it's preferable to work in localhost to test everything is ok and then re-upload the theme in order to prevent some common error that can make your site inaccessibile.

You can use software like MAMP(mac) or XAMPP(windows) to set up your wordpress site locally!

Take a look at this plugin WP Maintenance Mode

from the description: "Add a maintenance page to your blog that lets visitors know your blog is down for maintenance, or add a coming soon page for a new website. User with admin rights gets full access to the blog including the front end.

Activate the plugin and your blog is in maintenance-mode, works and only registered users with enough rights can see the front end. You can use a date with a countdown timer for visitor information or set a value and unit for information. Also works with WordPress Multisite installs (each blog from the network has it's own maintenance settings)."

maintenance mode plugin? whats this?

great thanks!
