求助:limesurvey使用过程中出现了问题,该怎么办

大家好,首次使用limesurvey做问卷,一共设计了5个题组,第二个题组和第三个题组问题都在375个左右,在测试调查的时候,第二个题组填写完问卷,出现了以下这种情况,并没有跳到第三个题组,该怎么办
404 Not found.
The survey in which you are trying to participate does not seem to exist. It may have been deleted or the link you were given is outdated or incorrect.
The requested URL was not found on this server. If you entered the URL manually please check your spelling and try again.

If you think this is a server error, please contact the webmaster.

补充:外观如果设置成每页显示一道题的话,整个调查是可以完成的;如果每页显示一个题组,那么只能完成两个题组之后就出现404 not found这种情况;如果设置将所有的问题显示在一页上的话,网页就打不开了。
这种情况可能是出什么问题了?谢谢大家
