11 Frequently Error When Upload WordPress Network Up And Use

This article is mainly for you are new to wordpress only, some doctor familiar with wordpress do not throw stones.

The first error is the database connection error

1.Error establishing a database connection

This error is so easy to edit, just check the file wp-config.php back

[Codesyntax lang = “php”]

define (‘WP_CACHE’, true); / / Added by WP-Cache Manager
define (‘DB_NAME’, ‘kaka’);

/ ** MySQL database username * /
define (‘DB_USER’, ‘root’);

/ ** MySQL database password * /
define (‘DB_PASSWORD’,”);

/ ** MySQL hostname * /
define (‘DB_HOST’, ‘localhost’);

/ ** Database Charset to use in creating database tables. * /
define (‘DB_CHARSET’, ‘utf8’);

/ ** The Database Collate type. Do not change this if in doubt. * /
define (‘DB_COLLATE’,”);

[/ Codesyntax]

attention to three parameters need to see is the database name, user name and password. Watch carefully and report back is ok.

One more thing to note is that user’s right, you have to full right then, if you forget the password or do not know how that user rights, you create another user and to inform the users that is ok, so is the fastest then.

2.Chi wealth are also a few other sites homepage error

This is the most common, you just on the home page but some pages not to be, in wp-admin still.

Resolved as follows, you log in to the admin and viewing permalink’re in, I think 90% is the mode you are in the post name. You just go to the permalink and click update is ok now.

When in localhost you should leave permalink in default mode, so you will not see this error, but any way you admin to update the permalink.

3 Admin page displays disorder in WordPress page

When you go to the admin page and display it without CSS, the path to the css file does not exist (do not load the css file), all the links are sorted by a disorder like this:

Solution 1: Proxy & Firewall

Please check your internet connection using a proxy or firewall or not. These often lock CSS files and make it not load into your admin page. Manually delete the proxies and firewalls cookies and cache, and then press F5 to reload the page.
Solution 2: Update to WordPress Plugins

If you have a set menu for the admin page as ‘Admin Drop Down Menu’ plugin or ‘Lighter Menus’ plugin, make the latest version update for it. If not yet, then deactivate the plugin.

4 Warning: Can not modify header information – headers already sent by

You receive an error message like this when on your website or blog:
“Warning: Can not modify header information – headers already sent by (output started at / path / blog / wp-config.php: 34)”
As soon as you update the new version for your WordPress or just install WordPress.

Solution:

Remove white space, newline or other unnecessary things in wp-config.php
1 Download wp-config.php with FTP
2 Open the file wp-config.php
3 Remove spaces before
4 Make sure the first characters in this file will be without a space in between

5 Remove all whitespace after?>.
mà không còn bất cứ một khoảng trắng nào.”>6 Make sure that the last character in the wp-config.php file is?> Without any spaces.

in php errors very frequently encountered, I will do an article about this issue later. You find all the characters, spaces outside “” It’s ok.

This error can occur in other files, so you should read carefully to portable specify the file and edit the same as above.
