这两天捣鼓Wordpress，遇到了无数的问题，估计Google不下百次，有些问题实在诡异，不过幸好都让我找到了答案。例如，昨天被这个问题搞得几乎崩溃：有的帖子在更新发布之后就变成空白了，刚开始我以为是数据库连接问题，后来在phpMyAdmin中检查了一遍又一遍，甚至直接更改数据库，都没法让文章显示出来，于是又去查codex，看`the_content()`等函数，依旧无果。最后在千般尝试下，发现把文章删除一部分文字之后就可以显示出来了，于是我意识到这与被删的文字有关，但从未听说Wordpress系统对文章内容有审查啊，所以应该不是关键词过滤的问题，我于是一句一句话地删除，看删到哪里之后文章就发不出了，最后统计了一下字节数，但这个数字对解决问题根本没用，因为不能因此就避免长文章。
