WAMP Installation Issue

Hello.

I am trying to install Contao 4 using Contao Manager.

While installing after some times I have received the below error.

ERROR 500 File "E:\wamp64\www\tests\cms\contao4\contao-manager/composer-install.get.json" does not contain valid JSON.

Looking forward to suggestion and help to resolve the issue.

Thanks.

Did you try it several times?

BTW: I wrote a tutorial that describes the installation of Laragon WAMP (in German though!). Maybe that could be useful to you, too.

Hello.

I proceed along with the installation process. After getting the error, I manually write URL to Contao Manager and then it starts and installed successfully. Now I can enter into the Admin Panel. But the front page is showing some error or no page.

Now I am trying to add a new free theme. But its not working. Any help would be appreciated.

Thanks.

Which theme would you like to add?

What is the default theme for Contao 4 and how to get it?
Also I wish to create my own theme with simple Header, Navigation, Sidebar, Content area, Footer.

There's no default theme at all. One might consider the Contao Official Demo as a reference to start developing a new theme.

You can get the COD

- via Contao Manager (search for contao/official-demo) or
- via console command: composer require contao/official-demo

Contao 4 demo is installing via Installer. After importing the database sql file receives the below error.

Code:

---

The import failed! Is the database up to date and is the template file compatible with your Contao version?

Here you can import an .sql file from the templates directory. Any existing data will be deleted! If you only want to import a theme, please use the theme manager in the Contao back end instead.

---

Also the database becomes empty and exisitng files are all lost. How do I install the demo? Please guide and help.

What is the name of the SQL template? And which Contao version?
