Solving The WordPress ‘you need to make this file writable’ Error Message
It depends on your web hosting service, but sometimes when I try to edit the theme on a new WordPress self-hosted blog, I get this error message..
‘You need to make this file writable before you can save your changes’
Here’s a short video on how to solve this problem, by setting the theme file permissions so editing is allowed.
IMPORTANT: Once you have finished editing your theme files, make sure you reset your file permissions to say 644. Just do it the same way, as shown in the video. It will help protect your website, going forward.
