Issue with my links or permalinks

1) add or edit the .htaccess file, it should be:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

2) Go to admin panel -> settings -> Permalink and select Post name, if this does not fix, then click on Custom Structure and write /%postname%/
