I don't know how, but today, the installation-window is working correctly. :)
I used the Test-Buttons and I don't get an error, but now, I have another problem. I filled out the form correctly and when I push the button "Install", I get an Error:
Warning: strlen() expects parameter 1 to be string, array given in C:\Programme\XAMPP\xampp\htdocs\TeamCalPro\installation.php on line 186
Warning: Cannot modify header information - headers already sent by (output started at C:\Programme\XAMPP\xampp\htdocs\TeamCalPro\installation.php:186) in C:\Programme\XAMPP\xampp\htdocs\TeamCalPro\installation.php on line 201
And the following one:
You already have an existing configuration file "config.tcpro.php" in your TeamCal Pro directory. If you run this installation again it will be overwritten. Also, if you use the same database settings as your current installation, the database will be ovewritten as well.
I deleted the config-file, but after that, the installation didn't work.
Where is the error?
