You open your site — or the admin panel — and there's nothing. No error, no message, just a blank white page. This is the "White Screen of Death" (WSOD), and it's one of the oldest, most common problems in the entire Joomla ecosystem. It's been happening since Joomla 1.5 and it still happens on Joomla 6, for the same underlying reason every time: something in the request chain is failing, and Joomla's own error handling never gets a chance to display anything about it.

At some point every Joomla site owner needs to touch a file that isn't an article or a module setting — editing robots.txt, fixing a typo in configuration.php, clearing a stuck cache folder, grabbing a log file to send to a developer, or patching a single line in a template override. The usual answer is "open an FTP client" or "log into cPanel's File Manager." But that's not always possible, and it's rarely convenient.

Choosing a template is the first real decision you make when building a Joomla site, and it's a more consequential one in 2026 than it used to be. Joomla 6 tightened its technical requirements (PHP 8.3+, MySQL 8.0.13+ or MariaDB 10.4+), dropped several legacy compatibility shims by default, and expects templates built on modern Bootstrap 5 markup. A template that hasn't been actively updated for Joomla 5/6 can break silently — missing styles, broken mega menus, or JavaScript errors from old jQuery-plugin syntax that Bootstrap 5 no longer supports.

Joomla 3 reached end-of-life on August 17, 2023 — no security patches, no bug fixes, nothing. If your site is still running on it, you're not just missing out on new features; you're running on software nobody is watching for vulnerabilities anymore. Joomla 6 is the current generation, and it requires PHP 8.3+ and MySQL 8.0.13+ (or MariaDB 10.4+), which tells you how far the gap has grown.
