From b2evolution manual
This manual page is outdated. NEW PAGE: Settings Tab in b2evolution v5+.
This is the tab for editing settings that apply to all blogs on your installation of b2evolution. Here you can set the default blog, change language settings and install plugins. There are several sub-tabs, and each is dealt with in a section below.
Note: since 1.8.1 the Settings tab is called App Settings.
 Default user rights
If you want to allow new users to register themselves, then enable it here and choose which group and user level you want the new user to have once they've registered. You can always put new users into a very limited group by default and then an admin can promote them later.
You can require users to validate themselves by clicking on a link that is emailed to them. This prevents users from signing up with fake email addresses.
 Display options
"Default blog to display" determines which blog will be shown when a readers goes to index.php. You can also set whether posts are considered individual units or are grouped by days. "Posts/Days per page" is where you set how many posts will appear on your front page and other pages.
After older posts have been moved off of your front page, you still want readers to be able to find them. The archive section in your blog's sidebar provides links to help. "Archive mode" is where you choose whether you want a link for each month, each week, each day or each individual post.
 Link options
This section gives you some control over the appearance of the permanent links of your posts and archives. "extra-path info:" is recommended if your webserver supports it. Links will look like 'stub/2006/05/20/post_title' instead of 'stub?title=post_title&c=1&tb=1&pb=1&more=1'. To get this working properly, you may need to rename the sample.htaccess file that you uploaded to .htaccess. Apache2 users can also uncomment the last line in that file. If you're still having problems, check with your web host to make sure that extra-path info is supported.
You may also change the permalink type. Unless you have a good reason not to, use the default, which is "Post called up by its URL title". Your links will be more meaningful.
 Security options
The default "Minimum password length" is five characters. In general, longer passwords are harder to guess or crack, but shorter passwords are easier for users to remember. If you're not sure, five characters should be fine.
 Miscellaneous options
"Reload-page timeout" is the time (in seconds) that must pass before a request to the same URL from the same IP and useragent is considered as a new hit. If you're not sure what that means, then just leave the default value (300).
 Online Help
Online help links provide context sensitive help to certain features.
 Blog by email
Check the box to enable blogging by email. Doing so will reveal the other settings you'll need to edit. For a more detailed look at this feature, see Email.
 Hit logging
Activating "Double-check Referer" will search the requested (your) URL in the content of the referring page. This is against referer spam, but creates additional webserver traffic.
By changing the "Autoprune stats" value, you can set how many days of stats are stored in the database.

The "Session timeout" value determines how long a user can stay inactive before they are automatically logged out. The default value is 604800 secconds, or one week.
b2evolution comes standard with several translations for backoffice and blog navigation text. In fact, you can have bloggers in several continents, speaking several different languages, all on one installation of b2evolution. This is the tab for controlling some of those settings. Individual users can also set their own default locale, and individual blogs can have their own locale.
 Regional settings
b2evolution gets the time and date from the server it's running on. But you may not live in the same time zone as that server. You can set the time difference here using a positive or negative number.
 Available locales
This section allows you to customize the installed locales. You can change the date and time format, the first day of the week and the language file. There is a link at the bottom of this section for creating a new locale.
See also Localization.
Here you can change the settings for the built in file manager, which is accessible from the files tab.
 Filemanager options
Installations with multiple users can
- Have all users upload files into the media directory directly, or
- Enable a directory within the media directory for each user, or
- Enable a directory within the media directory for each blog, or
- Enable a directory within the media directory for each user and each blog.
You can also control whether users are allowed to create directories and files.
 Upload options
Check "Enable upload" to allow uploading files in general. "Maximum allowed filesize" is the max size (in KB) of file that users can upload. This does not override your web server's maximum upload size. If you set this value higher than the server limit, your uploads may fail.
 Advanced options
These regular expressions set what characters can be used in file names and directories. Don't edit them unless you understand regular expressions.
 File types
In this sub-tab, you can control settings for file types. You can set the icon, extensions, name, mime type, view type, and whether users can upload this type of file.
If you create a new file type, put the icon in the /rsc/icons/fileicons/ directory.

Here you can setup the thresholds for deletion or moderation of comments and define the spam detection relevance weight of the plugins that provide a method to get spam karma.
Plugins are extensions to b2evolution that can be installed and used without the need to edit code. This tab is where you install and configure plugins.
 Installed plugins
This table lists all of the plugins that have been installed. You can activate and de-activate them, edit their settings, view their help files and uninstall them.
The link "Reload events and codes for installed plugins" should only be needed if you edit the plugin php file and add or remove events or change the plugins unique id code. Upgrading to a new version of a plugin may require using this link. Plugin developers will also find it useful.
 Available plugins .
Once a plugin file or directory has been added to the /plugins/ directory of b2evolution, the plugin will be listed in this table. It won't be listed in the table above until you click "install".
