In case your wao.io optimized website shows an unexpected behavior or even an error, there is no need to change your DNS settings back in the first place.
As follows you will find a quick and easy explanation on how to find out if this behavior is attributed to wao.io, or if you need to fix this on your server.

First, do a quick check and compare your optimized website against the unoptimized version. This can be done on your computer without making any changes to your site or name server settings.

How to bypass wao.io temporarily, only on your computer

 1. Edit your /etc/hosts file

On Windows, click Start  and type notepad , then right-click on the notepad icon and click Run as administrator

In notepad, open C:\Windows\system32\drivers\etc\hosts   

Add a new line with your website address and backend IP address, e.g.
87.79.3.153 www.makemywebsitefaster.com  

Finally, save the file and proceed with step 2.

On Apple MacOS or Linux, open a terminal window and edit /etc/hosts  as super user in a text editor, e.g.
sudo nano /etc/hosts  

Then add a new line with your website address and backend IP, e.g.
87.79.3.153  www.makemywebsitefaster.com  

Finally, save the file and exit the editor (in nano, press Ctrl+O , then Ctrl+X ).


 2. Make sure you switched to the backend version

Reload your website and make sure you're now seeing the backend version.
In Google Chrome or Mozilla Firefox, right-click anywhere inside your website and then click Inspect Element. The developer tools will open. Switch to the network tab, reload your site again, and click on the main entry.
You should see your backend's IP address on the right.

Alternative approach to verify the IP address:
Open a command window (Windows: click Start, then type command and click on the command icon, Apple MacOS / Linux: open a terminal window). Type:
 ping www.makemywebsitefaster.com  
and use your actual website address instead of www .makemywebsitefaster. com
You should see your backend's IP address in the output.

3. Verify your website's backend version in your browser
Check your website if everything is working as expected. Any problems than can be found in your website's backend version, are NOT caused by wao.io .

If your problem is gone when you bypass wao.io, modify your configuration and disable optimizations that have an unwanted impact on your site (see below).

 4. Switch back
After verifying your backend site, don't forget to undo your changes.
Remove the line you added to /etc/hosts  and save the file.

Then, reload your browser or use the ping  command to verify you are looking at the optimized version of your website again.

5. How to disable optimizations that turn out to be counterproductive

Login to wao.io and go to your website's settings.

If you already have an idea which aspect of your site is affected, try to disable the optimization related to that feature, e.g. if you experience problems with style sheets, try to disable CSS Minifying.

If you have no idea where to start, you can disable all optimizations, all security features and all advanced features and then, one by one, turn features back on.

After making a change, make sure to save your settings and reload your website.
