If you see "The webpage is not available", "We have trouble finding that site".

Answer: Your local webserver (Apache) is not running. Please start it via EasyPHP or MAMP control program/panel.

Answer: The server is running, but the application is not found. Maybe the Uniform Resource Identifier (URI) is wrong or misspelled. Please check/correct it. Or the URI is correct, and the application is installed, but not in the correct directory lwt below htdocs. Please install/copy/move it into the correct directory.

Answer: Either the database (MySQL) is not running, or the database connection parameters in ../htlwt/connect.inc.php are wrong. Please check/correct the database connection parameters and/or start MySQL via the MAMP or EasyPHP control program/panel.

Answer: The Webserver and the database is running, but the database connection parameter file ../htlwt/connect.inc.php is not found. Please rename one of the connection files (according to your server) to ../htlwt/connect.inc.php.

If LWT installed or updated LWT on Linux, but the application does not run as expected.

Answer 1: The Webserver does not have full access to all LWT files (insufficient rights). Open a terminal window, go to the directory where the directory "lwt" has been created with all LWT files, e. g.
cd /var/www/html
Now execute: sudo chmod -R 755 lwt.

Answer 2: The PHP "mbstring" extension is not installed. Please install it: see this article.
