OK, I had a site working and today when I went back to it some strange issues are happening. I'm not sure what I did, if anything. But more importantly, I can't figure out what to do!
Originally I had my .htaccess file set to remove the index.php from the URL. In the CP, under General Settings, I had the "Name of your site's index page" as blank (per a recommendation). Everything seemed to be working.
Today, any of my page links (ie mysite.com/page) simply show the home page (I've tested by adding and removing text from the home page template). I thought it was my .htaccess file so I replaced it with the one that Ellislab has in their documents. If I add the index.php back (ie. mysite.com/index.php/page), it works. However, the index.php is still showing up in the URL even though my .htaccess file is supposed to be removing it!
When I put my .htaccess file back, it removes the index.php, but then just shows the home page content again!
I don't know if I've inadvertently changed a setting or something, so any help or advice is greatly appreciated.
PS - This is an MSM site, and this is "Site 2" in the group. Again, it has been working the past few days while I was working on setting up the custom fields, etc....
