Help with SQL Backup / Demo Content

Hi people. I’v got a Theme wich comes with alternative demo content. there is a folder “uploads” with stuff for wp-content/uploads and a installer. the installer has only a .sql and .php inside, so i think it just chnges paths to the correct ones of my site.

iv got an ssl protocol installed. when i start the installer for the demo content, it destroys my wp setup. after it generate links like “https://https//mydomain.com/………….” and i cant access any site.

i attached the code of the installer
so my quastions / options:

how to fix the installer, so it wont destroy my setup and generate links correctly?

or how to install content manually, what i have to change in phpmydamin. maybe a coder can read it out of the code.

Thanks in advance.
