I'm rather savvy at WordPress, I swear. I've never seen this before, and yes, I've re-installed 5 times with fresh databases, and tried all kinds of things.
This is definitely an issue with my template. You see, whenever I load a post or page, they are getting loaded with the index.php template file instead of single.php or page.php ... I should mention this template is using a custom post type for product listings, along with custom taxonomies (tags/categories) for those custom posts. ALL custom items are working fine!
Has this ever happened to anyone???
For example, I load my site example.com/about/ and it does not show the propert content. It simply shows the index.php template file.
In addition, if I enter example.com/24ytoahg23oa4yh/ or other non-existing URLs, well, the 404 page/error is not getting displayed! Instead, WordPress is simply accepting it as a real URL and once again showing the index.php template.
And yes, I definitely have a page.php and single.php there...
Thanks ahead of time for any help!
