在Odoo中加载翻译后，有时会出现无法登陆的问题。前台页面错误信息如下，
Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

这时需要查看后台的提示信息，如果出现类似下面的信息:

bad query: SELECT value
                       FROM ir_translation
                       WHERE lang='zh_CN'
                        AND type in ('view')
                        AND src='Edit Company data' AND res_id=167 AND name='web
site'
...
QWebException: index "ir_translation_src_hash_idx" contains unexpected zero page
 at block 30
HINT:  Please REINDEX it.
则表明ir_translation表的索引出现了问题；根据提示，重构索引即可解决问题。方法如下:
(1)在数据库命令行输入命令: REINDEX INDEX ir_translation_src_hash_idx;
(2)也可通过pgAdmin操作，选定ir_translation表的ir_translation_src_hash_idx索引，点击维护，选择"REINDEX"。
