 * I tried to set up a page under a parent page and after I chose the parent page
   and published it I got this error while tryint to acces it : _Invalid File ID
   or File Name_. I wanted to have something like this : domanin.com/parent page/
   page and after publishing it gave me that error.

 * Did you amend the page permalink?

 * I meant did you originally amend the permalink before publishing the page?

 * Well the original permalink was domani.com/page1 and after adding the page under
   a parent it became domain.com/parent/page1 and that is where i got the error.
   Even when accessing domain.com/parent/page1 from the WordPress control panel.

 * Try resetting your custom permalinks back to the default setting. If that works,
   then set your custom permalink structure back up again.

 * Hmm but won`t that affect people that come to my site to certain pages? And if
   I switch it back will everything come back to normal?
    Hmm it looks like this
   problem occurs only when i try to add a certain page as parent. If i try to add
   a different page as parent everything is fine. And I`ve figured out the problem.
   The links are case sensitive, for example is I write the page names with capital
   letters the permalinks have small letters and it only works if I use capital 
   letters in the links, how can i do that?

 * Not if you set your custom permalink structure back up again once the problem
   has been resolved.
 * > I write the page names with capital letters the permalinks have small letters
 * That’s normal WP behaviour.
 * > it only works if I use capital letters in the links
 * Definitely sounds like a permalink problem. I’d suggest not only resetting the
   custom permalinks to the default settings but deleting/renaming your WP root .
   htaccess file as well.

 * Resetting the permalinks to their default setting is out of the question because
   I have a lot of people coming from links posted on other sites that go to specific
   pages, so I can`t do that. Won`t deleting the .htaccess file make my page unavailable?

 * Perhaps the problem is within the parent page. Is there anything that makes this
   page different from the others?

 * Not really, it’s a page named Download, and I want to add it as a parent for 
   another one. I really have no idea why only that page causes this… and it’s case
   sensitive, again, the only one.
    If I add other pages as parent everything works
   fine. I tried deleting it and adding it again, no chance, nothing works.. And
   on top of this I did a test today : added a page test and added that as a parent
   for page test 1 and everything worked fine.. why the Download page won’t allow
   this is beyond me .. I tried deleting the pages and adding them with lower case
   letters, again, this did not work..
