In our forum we are often asked to help with problems with paths,
passwords, data base connections and other basic configuration issues.
This is especially true after a migration or move of a site.
Most of the fixes for these problems can be made in your configuration.php file. We're going to help you get to know it this very important file.
$debug : This will turn on the debugging system of Joomla!. When set to Yes, this tool will provide diagnostic information, language translations, and SQL errors. If any such issues or errors occur, they will be displayed at the bottom of each page, in both the front-end and back-end.
$debug_lang : This will turn on the debugging indicators (*...*) or (?...?) for the Joomla! Language files. Debug Language will work without the Debug System tool set to on. But it will not provide additional detailed references which would help in correcting any errors.
You need this information when you install the site. Forgetting to change this is often the cause of problems when moving a site. Before moving any site, make a backup copy of configuration.php so you can refer to the original settings if you need them.
$dbtype : only change this if you have changed servers and using a different type.
$host : most servers this is localhost. Godaddy and a some others have different names. Check with your hosting company if you're not sure.
$user : On shared cPanel servers it is often prefixed with the user name - for example edandrea_ed. On your local machine there will not be a prefix unless you created one. It shouldn't be root in any case. If you create a site on your local server and don't specify password when you create a data base, you will be able to access the data without a password. This is not secure when you move to web server online.
$db : On shared cPanel servers this is usually prefixed with a username - for example edandrea_jml1. On your local machine there will not be a prefix unless you created one. On Godaddy servers this name is generated by their service and you will not be able to create your own, see their documentation if you need it.
$dbprefix : You cannot create a new one here. This must be the one that was used when the data base was created, or that is actually used by the database. If you have more than one data base prefix, you can change this, but you can't create a new one.
Most of the fixes for these problems can be made in your configuration.php file. We're going to help you get to know it this very important file.
In this lesson, were going to tell you:
- Where you can locate your configuration.php file.
- What each line affects and common settings.
Location of the configuration.php file
Here's a picture of the location using Filezilla. This installation is in a sub directory called "joomla" .
Your configuration.php file is located in the root of your joomla installation. If it's in the main directory the path to it would look something like this:
We'll go through the file line-by-line and create a quick reference for each line, with some notes where further explanation might be needed.
Your configuration.php file is located in the root of your joomla installation. If it's in the main directory the path to it would look something like this:
- /home/username/public_html/configuration.php
- /home/username/public_html/subdirectory/configuration.php
- C:\Documents and Settings\Ed\My Documents\xampp\htdocs\J17\configuration.php
We'll go through the file line-by-line and create a quick reference for each line, with some notes where further explanation might be needed.
Site Settings
- $offline : When set to "0" the site is online. Set to "1" the site is offline
- $offline_message : You can write any text message on this line.
- $sitename : The name of the site as it appears in headings
- $editor : The editor that is chosen as default in global configuration
- $list_limit :The length of lists in the Control Panel for all Users. By default, this is set to 20.
- $access : The default access level to the site. "1" is public access; "2" is registered; "3" is special
Debug Settings
- $debug : "0" is off. "1" is on.
- $debug_lang : "0" is off. "1" is on.
$debug : This will turn on the debugging system of Joomla!. When set to Yes, this tool will provide diagnostic information, language translations, and SQL errors. If any such issues or errors occur, they will be displayed at the bottom of each page, in both the front-end and back-end.

Database Settings
- $dbtype : "mysqli" or "mysql"
- $host : "localhost" on many servers, not all.
- $user : The name of the data base user that has access to the data base.
- $password : The password associated with the data base user. Not your admin password or FTP password.
- $db : The data base name created when you created the data base.
- $dbprefix : At least three characters ending in an underscore. (Set when you installed joomla)

Assorted extra features
$live_site : The actual URL of the site for example - http://yourdomain.com (unless your site is in a subdirectory)
$secret: : DO NOT CHANGE
$gzip : "0" is off; "1" is on.
$error_reporting : "-1" is the appropriate level.
$helpurl : default is joomla help. Can be set to your own help pages.
Notes
$live_site : In the newest versions this should not have a value. There may be times you do need to fill in a value. If you are redirecting a url you need to put the actual url to the live site on this line. Or if you are creating a copy of a site for testing and modification. For example, I have a test site at http://dashhelp.com/joomla17 which is a copy of my main site. had to change this to line in the configuratiion.php file on the copy. You will get a page not found error if this is not set to 'http://yourdomain.com/directory" or in the case of a subdomain "http://subdomain.yourdomain.com" Joomla uses this url to create relative paths. Essential to check this on test sites.
$secret : This is generated when Joomla! is first installed and is not changeable. It is used internally by Joomla! for security purposes.
$error_reporting : This sets the appropriate level of reporting. The default setting is System Default. Errors can occur that don't have any effect on the site. You don't need to log all errors unless you're doing some detailed debugging work. Your logs will just eat up your disk space otherwise.
$helpurl : The place Joomla! looks for help information when you click the Help button (visible in many screens and options of the administration panel). By default, it uses Joomla!'s main help site, but you could create your own help site, or link people to your ticket system for help.

Log Settings
$log_path : '//home/username/public_html/j/logs';
$tmp_path : :'//home/username\public_html/tmp';
Notes
$log_path : The path where the logs should be stored. The Joomla! installer should automatically fill in this folder. It's not critical to the operation of the site, so if it's wrong you will only know it if you try to check the logs.
$tmp_path : This is an important setting and should be filled in properly. Many problems found when moving sites are caused because joomla is looking for the old tmp folder. If you get any errors regarding the tmp folder check this path and make sure it's correct..

SEO Settings (Search Engine Optimization)
$sef : "0: is no; "1" is yes
$sef_rewrite : "0" is no; "1" is yes
$sef_suffix : "0" is no; "1" is yes
$unicodeslugs : "0" is no; "1" is yes
$feed_limit : default is 10 - any integer can be used
Notes
$sef : This controls Search Engine Friendly URLs. When set to Yes, URLs are rewritten to be more friendly for search engine spiders. For example, the URL: www.example.com/index.php?option=com_content&view=etc..., would turn into: www.example.com/alias. Most of the items created in Joomla! have an Alias box where a search engine friendly URL can be inserted. The default setting is No.
$sef_rewrite : When set to Yes, Joomla! will use the mod_rewrite settings of Apache when creating search engine friendly URLs. Please note: it is advised that you do not modify any .htaccess file without an understanding of how it works. You must use the .htaccess file provided with Joomla! in order to use this setting. To use this file, rename the htaccess.txt file (found in the root directory) to .htaccess. By default, this setting is set to No.
$sef_suffix : When set to Yes, Joomla! will add .html to the end of the URLs. The default setting is No.
$unicodeslugs : Choose between transliteration and unicode aliases. Transliteration is default. This is an advanced setting and you probably will not need to change this unless you are and SEO expert.
