Update:
- Website address is bees.com.au
- Hosted on Google Cloud Platform using PrestaShop Click to Deploy
- Cache has been cleared after enabling Friendly URL and error persists
- All pages return the 404 error (i.e. content and product pages) except for the homepage
- Disabled Apache's MultiViews option and no change
- Change code in /etc/apache2/apache2.conf from:
<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
To:
<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride All
</Directory>
And it didn't fix the problem either.
