IMJZ刚建成就有更新，当然要升级咯。
第一次升级可不能马虎，怀着惴惴不安的心情点了升级，
郁闷，果然出错了。
google了下，还好解决方法不太麻烦。http://wordpress.org/support/topic/194370
Here’s the full solution in the cleanest possible way:
- Create a file called php.ini in the root of your site (if you are using a hosted addon domain, this must be in the subdirectory of that site)
- In php.ini, enter a line that says
memory_limit = 64MB- In your site’s .htaccess (being a WordPress blog, I’m assuming there is one), enter the following line
SetEnv PHPRC /<unix path to the directory where php.ini is>/
(keep the slashes)- Edit wp-config.php and enter the following line
define('WP_MEMORY_LIMIT', '64M');- Upload the new files to the server
Oh, and don’t tell your hosting provider you’ve done this…
租用的空间改php.ini 比较麻烦，按照第四点，改了wp-config.php，升级OK。
