Fatal error: Call to undefined function: populate_options() in /wp-admin/upgrade-functions.php on line 7

然後我很倒楣地發現
UGtech的Fantastico似乎有提供upgrade的功能

Use Fantastico to automatically install any of the scripts listed on the left. Installing any script will use one of your available MySQL databases. Removing any script will free up one of your used MySQL databases.

Click on any of the items on the left to get more details.

UPDATE NOW!
Following installations are not up-to-date. Keep your installations secure and up-to-date and ensure that future versions of Fantastico will be able to maintain your installations by updating now.

由於Fantastico判斷不出來WP的版本

Current installations:
/wp (unknown)      
Only manual upgrade possible

所以只能手動安裝
我只好備份檔案及資料庫
從Fantastico反安裝WP後
再行安裝一次囉

因此請忘川水親愛的讀者
在techblog主機送修以及孟婆湯再次安裝期間
改道blogsome吧
