Click on the left navigation on Borlabs Cache > Dashboard.
Select the checkbox at Activate Borlabs Cache and under Cache Presets select Default. Now click on Save all settings.
Borlabs Cache differs between an active and inactive configuration, so whenever you change settings, you have to apply them. After you clicked on Save all settings
Now click on Apply changes and refresh cache to make your current configuration your active configuration. Open a browser in private mode to test if your site works like before (of course, way faster ;-)).
If your site looks broken, try another Cache Preset like Test CSS or Test JS. If it is still not working and you feel completely lost, click on Borlabs Cache > Support and get in touch with us.
