Permalinks

I changed my permalink structure to pretty permalink to only display the post name.
I cannot edit the permalink for my posts when i click the edit button underneath the post title.
Instead #post_name appears. The link shows up as
https://thebudgetblog.com/wp-admin/post.php?action=edit&post=9#post_name
and nothing happens!
Also my blog title image disappears when i try to view a single post
homepage: https://www.thebudgetblog.com
single post page: https://www.thebudgetblog.com/destination-procrastination
I changed the htc access file to file permission 666 and added the statement
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
