Discuz安装插件后网站出现500如何解决

<font color="#ff0000">安装了几款视频播放插件,但是一打开帖子页就出现500,然后在网上找了一个答案不知道对不对</font><br /><font color="#ff0000"><br /></font><br /><font color="#ff0000">下面是找的答案</font><br />尽管目前discuz已经升级到X3.4版本了,但是X2.5版本还有很多站长在使用。目前使用X2.5版本的站长面临的一个很头疼的问题就是好多插件不支持了,或者安装插件直接显示500错误,<br />具体表现为:安装没有前台界面的插件就可以正常使用,但是安装有前台界面的插件就打开报错!<br />这个问题一般是由于X2.5模板解析机制不同导致的,凡是在模板中调用系统函数或者自定义函数的都会出现此类错误,经过与高版本discuz!对比,发现修复方法如下:<br />打开文件 \source\class\class_template.php<br />找到代码<br />&nbsp; &nbsp; &nbsp; &nbsp; function stripblock($var, $s) {<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $s = str_replace('\\&quot;', '&quot;', $s);<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $s = preg_replace(&quot;/&lt;\?=\\\$(.+?)\?&gt;/&quot;, &quot;{\$\\1}&quot;, $s);<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; preg_match_all(&quot;/&lt;\?=(.+?)\?&gt;/e&quot;, $s, $constary);<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $constadd = '';<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $constary = array_unique($constary);<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; foreach($constary as $const) {<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $constadd .= '$__'.$const.' = '.$const.';';<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $s = preg_replace(&quot;/&lt;\?=(.+?)\?&gt;/&quot;, &quot;{\$__\\1}&quot;, $s);<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $s = str_replace('?&gt;', &quot;\n\$$var .= &lt;&lt;&lt;EOF\n&quot;, $s);<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $s = str_replace('&lt;?', &quot;\nEOF;\n&quot;, $s);<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return &quot;&lt;?\n$constadd\$$var = &lt;&lt;&lt;EOF\n&quot;.$s.&quot;\nEOF;\n?&gt;&quot;;<br />&nbsp; &nbsp; &nbsp; &nbsp; }<br />在代码$s = str_replace('&lt;?', &quot;\nEOF;\n&quot;, $s);下方加上一行:<br />$s = str_replace(&quot;\nphp &quot;, &quot;\n&quot;, $s);<br />上传覆盖此文件,然后将 \data\template目录中的内容清空。<br />修复完成!<br /><font size="4"><br /></font><br /><br /><font size="4"><font color="#ff0000">在代码$s = str_replace('&lt;?', &quot;\nEOF;\n&quot;, $s);下方加上一行:</font></font><br /><font size="4"><font color="#ff0000">$s = str_replace(&quot;\nphp &quot;, &quot;\n&quot;, $s);&nbsp; &nbsp;这一行代码里面已经有了</font></font><br /><br /><font size="4"><font color="#ff0000"><br /></font></font><br /><font size="4"><font color="#ff0000">将</font></font><font color="#ff0000">\data\template目录中的内容清空,这个我不敢清空,因为我不知道</font><font color="#ff00">template目录中的内容是干嘛的,清空会不会导致更严重</font><br /><font color="#ff00"><br /></font><br /><font color="#ff00"><font size="5">知道的老哥麻烦解答一下,谢谢!!</font></font><br /><br />插件<em>, </em>版本<em>, </em>replace<em>, </em>constary<em>, </em>ff0000

找这插件开发老哥解决了,他的两个插件同时用的话有冲突,下次安装插件出现这种情况 可以一个个插件关闭,每关闭一个插件刷新去看看是不是正常了,不正常的话又继续关闭另外个插件
