With version older than 2014-08-10, you should put ~~NOCACHE~~ in the pages where you use this plugin, to make sure that if you create or remove a page in the namespace, it will be taken into account. Now, nspages automatically deactivate the cache on the pages where it is used (you can deactivate this behaviour on the admin panel). The CSS sheet should be taken into account in order for this plugin to work correctly; but because of the cache system it may not be the case the first time you use this plugin (even if ~~NOCACHE~~ is specified). The easier way to resolve this is to make sure your cache is invalidated by touching conf/local.php (eg. by resaving your configuration) Currently, you may not use a > in the -textPages and -textNS options, since it is understood as the end of the tag
