Thank you for your reply.

I have published my website and it is still under construction.

http://laakir.com/index.html

I need to change or replace the template because it is so bigger for smartphones. And also I need to know more information about how to receive emails from the users. ( access and data management)

I have a problem that Once you export your website online, you will find the diagnostics information related to the server in the WebSite Test section of the Online Control Panel or in the WebSite X5 Manager App if you are a Pro edition user.
Thank you

"I need to change or replace the template because it is so bigger for smartphones." - you can change the template to another one, but I would advise you to just work on the current template, but for different screens.

"And also I need to know more information about how to receive emails from the users. ( access and data management)" - here may be useful information for you.

And here are paid video lessons, which may be useful information for you.
