Incorrect Re-direction to localhost:8888/site

Hi I have an install on my localhost (PC) that has been working fine up until now. I can log in to the backend no problem (localhost/site/wp-admin) but the frontend is re-directing to localhost:8888/site.

I have checked the DB and made sure the siteurl and homeurl are both https://localhost/site. I don’t know where it’s getting the MAMP home directory from. I have also tried resetting permalinks from the backend, dropping database and re-importing and have checked the htacess file which is as below:

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

Any help would be greatly appreciated. Have no idea where else to go to try and fix this.
