Drupal 7.x

In my admin menu, I get a flag that settings.php is a security risk because it is still writable.

I checked and the only person with permission to write to it is me the owner.

Am I supposed to change it so noone, even me, can write to it?

Doesn't Drupal need the ability to change it, or is it a case of once set up, no one should have permission to write to it again?

I have created a moderator role, which should be able to administer users.
When a user with moderator role logs in and view the user listing page, the administrator user is also enlisted on the page. This means that the moderator can edit, delete the administrator account. Is there any method to restrict this without changing the drupal core? Is this point the drupal developers ignored? because this scenario seems very irrelevant.

I downloaded and installed the basic theme (drupal 7) and loaded it into my sites/all/themes directory. I made some changes to the CSS and decided that I was not keen on them, so decided to try another core theme. I tried stark and got a large list of warnings. I restarted the browser and the stark theme was installed. When I went to the settings page for the stark theme and changed the default logo for one of my own (using the path and browser button) and saved it it brought back the basic theme that I'd used earlier.

Good day,

I installed Drupal 7 yesterday for a new website of mine. The site is www.acutens.nl and it's hosted at www.one.com.

The issue is that the standard theme (Bartik) works fine until the moment that I change the colors of the theme. As a result I get a website with no colors and no standard logo image.
After checking back and forth, the folder sites/files/color/bartik-xxxx and its contents are created: logo.png and color.css

I have a prototype site working in English. I have installed modules 'variable' and 'i18n'. How do I add Chinese? For example, the first menu item is "Home"; how do I get it to appear as "首頁"?

* In Administration > Configuration > Regional and language >
There are two languages defined; English (the default) and Traditional Chinese. Both are (now) enabled.

I am using the media-gallery module to create dynamic galleries for a site.
I have a problem when I edit a node; I get the following error:

Notice: Undefined index: media_gallery_format in locale_field_node_form_submit() (linea 405)

I have read Undefined indexes in locale_field_node_form_submit(), but I didn't resolve the problem. The issue report suggests that the error depends from a local language, and that I should change one line in media-gallery.module, but I don't understand where that line is, and how to change the code.
