A completely blank page is often caused by an out-of-memory error in PHP. If 
this is the case, there might be some information about the crash in the 
server logs.

Your pagelist is caching a number of sections of each page, and it is possible 
that at 306 pages this goes over the memory limit. And with a different 
pagelist template caching less page data, it could work fine.

If the memory limit is your problem, you can raise this limit in php.ini, the 
PHP configuration file, where you can change the line to:

  memory_limit = 48M

  See http://php.net/manual/en/ini.core.php#ini.memory-limit
