O.K. so I went into the wp-includes/vars.php file and made the changes suggested in the link above and word press still cannot write to .htaccess.
Steps to enable permalink:
1.structure: /%year%/%monthnum%/%day%/%postname%/
2.Click on “Update Permalink Structure” tab
3. Get following error message: “If your .htaccess was writable we could do this automatically, but it isna€?t so these are the mod_rewrite rules you should have in your .htaccess file. Click in the field and press CTRL + a to select all.”
4 So I copy and paste rules into .htaccess file
Now once I do this, whenever I hover over the post title, it shows the new link structure but whenever the link is clicked, I get a 404 page.
Can someone tell me why?
