1. Give Yourself Permission

If you are new to google cloud then maybe you have not given permission to yourself to edit these files.

Go to Compute Engine > VM Instances >

Select the instance and click on SHOW INFO PANEL button

Now click on “Add members” button and add yourself here.

2. Enable mod_rewrite in Apache

This can be done by going through Compute Engine>VM Instances > and to the far right on the line will be SSH. Click it and select “Open in Browser window” it will take you securely inside a command line interface. Now run this command:

sudo a2enmod rewrite

3. Enable Apache AllowOverride

Use this command to modify the file:

sudonano /etc/apache2/apache2.conf

Once you’re in there, find the right spot and change it(you may find this code by moving the cursor down by 50 lines or more…)

<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride ALL <—-(edit from none)
Require all granted
</Directory>

After you’ve made that change(Replace NONE with ALL), make sure to restart the server by running this command:

sudo service apache2 restart

4. Your are done now, your .htaccess file should work.

Now go for permalink changes in WordPress, it will work.
