		<description><![CDATA[最近一个多月来发现blog流量突然锐减到以前的一半，虽然以前访问量也不多每天也就100多IP但突然变成每天只有40-50的状况就很奇怪。而且发现我自己用IE7无论如何都无法打开blog，很是郁闷，但又对这个问题没有丝毫头绪，烦哪。 具体症状是这样的： Blog用IE浏览器无法打开，或者打开后会不断的自动刷新，而用Firefox和Chrome却可以正常打开。 碰巧前几周赶上“暴风门”（国内主干DNS服务器瘫痪和DNSPOD被攻击）的事情以为是受到了此类事件的影响也就没多考虑，直到上月31号在RSSA群里请教了几位高人才得知可能是插件的问题。 &#160; 于是想了想最近装过的插件都是哪些，一个个停掉，等把WP Super Cache停掉后终于发现Blog不会自动刷新而且IE也可以打开了，激动！ 二话不说，直接卸载掉，谁让你破坏我的blog来着 。 而之后blog的访问量立马回升，当天就基本恢复到了以前的水平 （当然了，以前用IE不能打开的同学现在都可以打开，流量当然会恢复。）看着访问量图示里这个“龙抬头式”的曲线真高兴啊。 事后觉得有点奇怪，这个插件我很早就装了为什么那时候没出问题偏偏等到最近才出了问题？去看了下WP Super Cache的更新记录算是明白了，这个插件最近一次更新是在2009-04-25，刚好是我的blog出事的日期附近。去Google了下发现篮球博客也遇到了因WP Super Cache引起的问题，时间也是在4月25日左右。看来是最新版的问题，这个有问题的版本号是0.9.4.3。 但是总觉得不用这个如此好用的WP性能提升插件太可惜了，而且它有50W还多的下载量怎么就没把这个大bug给爆出来呢？唔， 我怀疑是跟某个已安装的插件产生了冲突，于是又开始折腾（我总是喜欢折腾…囧）。又安装了一次WP Super Cache，然后把最近安装的几个插件挨个停掉然后用浏览器测试，果然抓到只“灰老鼠”——GZippy（可以激活WP内置的gzip压缩功能），这东西效果貌似不是特别明显，直接删掉！顿时，世界清静了 。 总结： 多关注自己的blog的访问情况，以免延误发现问题。 当blog出现问题的时候需要耐心检查，尤其是要注意最近安装/更新过的插件，一个都不能放过。 WP Super Cache跟Gzippy一定不能同时开启！ P.S.测试的时候还试过跟WP Super Cache功能类似的插件Hyper Cache，结果这个插件装上后遇到的问题比之前的还严重，首页全是乱码。<table class="wumii-related-items" cellspacing="0" cellpadding="3" border="0"  style="clear: both;">

			<content:encoded><![CDATA[<p><img style="display: inline; margin-left: 0px; margin-right: 0px" height="160" src="http://lh4.ggpht.com/_xolacdOPHS8/SiTfW5XMA6I/AAAAAAAABHA/LwurX2EBFHA/s800/WP Super Cache.png" width="325" align="right" />最近一个多月来发现blog流量突然锐减到以前的一半，虽然以前访问量也不多每天也就100多IP但突然变成每天只有40-50的状况就很奇怪。而且发现我自己用IE7无论如何都无法打开blog，很是郁闷，但又对这个问题没有丝毫头绪，烦哪。</p>
<p>具体症状是这样的：</p>
<blockquote><p>Blog用IE浏览器无法打开，或者打开后会不断的自动刷新，而用Firefox和Chrome却可以正常打开。</p>
</blockquote>
<p>碰巧前几周赶上“暴风门”（国内主干DNS服务器瘫痪和DNSPOD被攻击）的事情以为是受到了此类事件的影响也就没多考虑，直到上月31号在<a href="http://www.onlyalizee.cn/rssa-blog-union/" target="_blank">RSSA</a>群里请教了几位高人才得知可能是插件的问题。</p>
<p>&#160;</p>
<p> <span id="more-642"></span>
<p>于是想了想最近装过的插件都是哪些，一个个停掉，等把<a href="http://wordpress.org/extend/plugins/wp-super-cache/" target="_blank">WP Super Cache</a>停掉后终于发现Blog不会自动刷新而且IE也可以打开了，激动！ 二话不说，直接卸载掉，谁让你破坏我的blog来着<img alt="" src="http://www.zu14.cn/coolemotion/emotions/zz_20.gif" /> 。</p>
<p>而之后blog的访问量立马回升，当天就基本恢复到了以前的水平<img alt="" src="http://www.zu14.cn/coolemotion/emotions/zz_16.gif" /> （当然了，以前用IE不能打开的同学现在都可以打开，流量当然会恢复。）看着访问量图示里这个“龙抬头式”的曲线真高兴啊。</p>
<p><img title="“龙抬头式”的访问量曲线" style="display: block; float: none; margin-left: auto; margin-right: auto" alt="“龙抬头式”的访问量曲线" src="http://arscat.com/pika/readimg.php?src=http%3A%2F%2Flh5.gouride.com%2F_xolacdOPHS8%2FSiTfBoUKegI%2FAAAAAAAABG8%2FrrkkKxamImQ%2Fs800%2FVisitors.png" /> </p>
<p>事后觉得有点奇怪，这个插件我很早就装了为什么那时候没出问题偏偏等到最近才出了问题？去看了下WP Super Cache的更新记录算是明白了，这个插件最近一次更新是在2009-04-25，刚好是我的blog出事的日期附近。去Google了下发现<a href="http://lanqiuboke.com/2009/04/25/wp-super-cache-problem" target="_blank">篮球博客</a>也遇到了因WP Super Cache引起的问题，时间也是在4月25日左右。看来是最新版的问题，这个有问题的版本号是0.9.4.3。</p>
<p>但是总觉得不用这个如此好用的WP性能提升插件太可惜了，而且它有50W还多的下载量怎么就没把这个大bug给爆出来呢？唔， 我怀疑是跟某个已安装的插件产生了冲突<img alt="" src="http://www.zu14.cn/coolemotion/emotions/zz_15.gif" />，于是又开始折腾（我总是喜欢折腾…囧）。又安装了一次WP Super Cache，然后把最近安装的几个插件挨个停掉然后用浏览器测试，果然抓到只“灰老鼠”——<a href="http://wordpress.org/extend/plugins/gzippy/">GZippy</a>（可以激活WP内置的gzip压缩功能），这东西效果貌似不是特别明显，直接删掉！顿时，世界清静了<img alt="" src="http://www.zu14.cn/coolemotion/emotions/zz_1.gif" /> 。</p>
<p>总结：</p>
<ul>
<li>多关注自己的blog的访问情况，以免延误发现问题。</li>
<li>当blog出现问题的时候需要耐心检查，尤其是要注意最近安装/更新过的插件，一个都不能放过。</li>
<li>WP Super Cache跟Gzippy一定不能同时开启！</li>
</ul>
<p>P.S.测试的时候还试过跟WP Super Cache功能类似的插件<a href="http://wordpress.org/extend/plugins/hyper-cache/" target="_blank">Hyper Cache</a>，结果这个插件装上后遇到的问题比之前的还严重，首页全是乱码。</p>
