This blog will help you to view the module positions of your Joomla template.
Go to Administrator > Extensions > Template Manager
In the Template Manager, go to Options in the right-hand side top of the screen.
Then in the Template Manager Options change the Preview Module Positions to Enabled, save and close.
Now you can view the module positions in the front end of the website by simply writing “?tp=1” to your index.php page. Example: If your domain name where the Joomla is installed is https://www.infyways.com, you need to write https://www.infyways.com/index.php?tp=1 to view the module positions.
If you still can’t see the module positions, then there is something wrong with you Joomla setup or installation. You can reinstall the Joomla and follow the same process.
