If you spend a lot of time revising a page or a post, you can build up quite a number of revisions in the database.
The following line in the wp-config.php file in the root of the site will limit the number of revisions saved to 5. You can use whatever number you want, within reason.
define('WP_POST_REVISIONS', 5); |

Moving a WordPress blog to a new domain   or web host may be easier than you think.
That's all there is to it. Don't forget to redirect your domain to the new server if applicable.
Periodically WordPress must be updated.
You can determine the current version of WordPress by looking at the source code of the a post. (Right-Click on the page and select View Page Source.) You'll see a line similar to the following approximately 20 lines down.
Once in the WordPress Dashboard you will see a message like "WordPress 2.8.4 is available! Please update now." across the top if an upgrade is due.
Users reasonably comfortable with MySQL and with access to the server should install the MySQL Administrator and MySQL Query Browser from the MySQL Website to assist with database management. It's a much easier way to work with your database, and it's not all that complicated. I find MySQL Administrator a much easier way to work with databases that a web-based tool like phpMyAdmin.
Follow the following process to do the backup.
/wp-content/ folder, though a full backup of the site can be made./wp-content/ will become /wp-content.284.disabled/.By default, geshi-derived syntax highlighters use a serif font to display code blocks. Many people find serif fonts less clear than the visually simpler sans-serif fonts.
A good choice is Lucida Console. Consolas is even better because it has a slashed zero, which is easier to distinguish from the capital letter "O", though not as many computers have Consolas installed. To account for this, list the fonts in order of preference, the browser will use the first one that it can display.
To change the default font for code blocks, find the geshi code folder (usually under plugins), open geshi.php and look for the following code:
1 2 3 4 5 | /** * The overall style for this code block * @var string */ var $overall_style = 'font-family:monospace;'; |
And modify is as seen here. Note that two word font names must be quoted, and the quote marks may need to be escaped, as seen below;
1 2 3 4 5 | /** * The overall style for this code block * @var string */ var $overall_style = 'font-family:Consolas, \'Lucida Console\', monospace;'; |
WordPress can have the disconcerting habit of inserting a space between the < and ?php when you want to show a code block in a syntax-highlighter plugin. To cure this, go into your WP Admin page, select the Settings menu, Select the writing submenu, then uncheck the WordPress should correct invalidly nested XHTML automatically option.
