好的，所以我正在搞乱插件wc3缓存插件试图让它绕过移动设备在wordpress这个服务器错误弹出。我是一个新手，每当弹出一些东西我通常会进入cpanel，删除它，一切都是hunky dory不是这次。我明白了：

我完全不知道我在做什么，所以我不想触摸它。
答案 0 :(得分：1)
这是坏线：
RewriteCond %{HTTP_USER_AGENT} (adsbot-google|android|bada|bb10|blackberry 9350|blackberry 9360|blackberry 9370|blackberry 9380|blackberry 9780|blackberry 9790|blackberry 9800|blackberry 9810|blackberry 9850|blackberry 9860|blackberry 9900|blackberry 9930|blackberry9500|blackberry9520|blackberry9530|blackberry9550|cupcake|dream|froyo|googlebot-mobile|incognito|iphone|ipod|s8000|webmate|webos) [NC]
错误消息指的是。 Apache对解析指令非常愚蠢，并假设空格分隔了指令参数（除了少数例外，比如用引号括起来）。这意味着当Apache尝试解析上述重写条件时，它会假设：
RewriteCond是指令%{HTTP_USER_AGENT}是第一个参数（要测试的对象）(adsbot-google|android|bada|bb10|blackberry是第二个参数（测试）9350|blackberry是标志还有更多的空间，但很可能Apache忽略了它们，因为它挂起了旗帜。显然，9350|blackberry不是有效的重写条件标志。它首先需要方括号内的东西，如[NC]为“无案例”，即使它在方括号中，它们也无效。
尝试使用\转义空格：
RewriteCond %{HTTP_USER_AGENT} (adsbot-google|android|bada|bb10|blackberry\ 9350|blackberry\ 9360|blackberry\ 9370|blackberry\ 9380|blackberry\ 9780|blackberry\ 9790|blackberry\ 9800|blackberry\ 9810|blackberry\ 9850|blackberry\ 9860|blackberry\ 9900|blackberry\ 9930|blackberry9500|blackberry9520|blackberry9530|blackberry9550|cupcake|dream|froyo|googlebot-mobile|incognito|iphone|ipod|s8000|webmate|webos) [NC]
或者你可以简化正则表达式：
RewriteCond %{HTTP_USER_AGENT} (adsbot-google|android|bada|bb10|cupcake|dream|froyo|googlebot-mobile|incognito|iphone|ipod|s8000|webmate|webos|backberry95[0235]0) [NC,OR]
RewriteCond %{HTTP_USER_AGENT} blackberry\ (93[5-8]0|97[89]0|98[0156]0|99[03]0) [NC]
