surya90 this file is used as the maintenance mode in the default Laravel application, but it cannot be used on Foodomaa as Foodomaa is built with React on the front-end.
The only way you could use maintenance mode is to:
- Integrate Cloudflare CDN (to clear cache easily)
- Create new index.html file and take a backup of the original one.
- Purge cache in Cloudflare.
And when you are done with maintenance mode, you will bews to revert back to the original index.html file and again follow the #3rd step.
