Problem: Site is multilingual, and I use translation for select list values. It works fine on the input data form (edit mode), but on "view", the saved values are shown in English and not in site's language.
Solution:
1. Go to the content type's Manage Display tab.
2. Change the Format value, next to the select list fields from 'Default' to 'Default translated'

I found the solution here: https://drupal.org/node/1101128

I followed this link:

Usually works: Create style-rtl.css (textual blank file) in addition to existing style.css file, and use it to override default LTR and align left definitions.
For example, add the following, ,to the empty styel-rtl file:

Duplicate existing data field of a content type

1. Edit your content type: Go to Structure » Content types . On the MANAGE FIELDS tab, Add new field. Use the same FIELD TYPE as in the field you want to duplicate. Save
2. Still in content types: Go to the MANAGE DISPLAY tab, and verify that the new field is visible (it is not displayed under Hidden)

• After installation goto https://drupal.org/node/275705
• Install Internationalization and Variable module
• Enable Locale, Contact and Content translation in Core
• Enable Variable, Variable realm and Variable store in Variable

Problem:

One of the users couldn't login to the site. After a few attempts the Sorry, there have been more than 5 failed login attempts for this account. It is temporarily blocked. Try again later or request a new password. message was displayed.
I entered the interface as admin, and went to this user's editing form. The user status presented was Active. I resetted the password, and tried to login as that user, but got the same error message.

No need to create a menu item for each language. Create items only for one language and use the Translate tab (next to Edit menu link), to translate to the other languages.

• Locate the translation file: Go to https://localize.drupal.org/, click on the required language name, you will be redirected to the selected language's translation page.
• Download the file that is relevant to your version (I downloaded the file next to 7.22, on the Drupal core project). It should have .po extension.
• Go to the file system: Go directly to your file system on your localhost, use an ftp client or the control panel for your hosting server file system.

• Download current version from https://drupal.org/project/drupal [I downloaded 7.22].
• Unzip and rename default drupal-7.22 directory to project name of your choice [I used “knowledge”]
