Fixing TestLink Blank Pages

Encountering a blank page in TestLink can result in various issues. Common causes and their solutions include:

Missing PHP Extensions

TestLink relies on certain PHP extensions, such as php-mbstring.
Solution: Install the required extension and enable it in your php.ini file. For instance, on Linux, you can install php-mbstring using:

$ sudo apt install php-mbstring

Then, enable it in php.ini by adding:

extension=mbstring

After making these changes, restart your web server.

Deprecated PHP Functions

Using outdated PHP functions like __autoload() can lead to compatibility issues.

Solution: Replace deprecated functions with their modern equivalents. For example, replace __autoload() with spl_autoload_register(). Locate the deprecated function in your codebase and update it accordingly.

Database Connection Issues

If TestLink cannot connect to its database, it may display a blank page.

Solution: Ensure that your database server is running and that TestLink’s configuration points to the correct database credentials. Check for any firewall rules that might be blocking the connection.

File and Folder Permissions

Incorrect permissions can prevent TestLink from accessing necessary files.
Solution: Verify that TestLink’s directories and files have the appropriate read and write permissions. On Linux, you can adjust permissions using:

$ sudo chown -R www-data:www-data /path_to_testlink_directory
$ sudo chmod -R 755 /path_to_testlink_directory

Replace /path_to_testlink_directory with the actual path to your TestLink installation.

Web Server Configuration

Misconfigurations in your web server can lead to improper handling of PHP files.
Solution: Ensure that your web server (e.g., Apache or Nginx) is correctly configured to process PHP files. Check the server’s error logs for any indications of misconfigurations.

This will help identify any underlying PHP errors causing the issue. By systematically checking these areas, you can identify and resolve the cause of the blank page in TestLink.
