Source: https://github.com/sebiboga/testlink-upgraded/issues/426 Status: CLOSED (fix already on default branch; verification & docs completed by this run)

TLSmarty hardcodes its Smarty search path to gui/templates/dashio/… (lib/functions/tlsmarty.inc.php:102), while templateConfiguration() (lib/functions/common.php:901) derives the template name from the script path. Eight scripts therefore rendered .tpl files that existed only under the legacy gui/templates/tl-classic/ tree → every visit died with Smarty: Unable to load template 'file:<name>.tpl' (HTTP 500).

Method chosen: straight port (copy) of the 8 templates into dashio — the intended approach per the audit (the sibling resultsTCFlatLauncher.tpl is byte-identical between themes). This landed on the default branch as commit 764d625e1. Alternatives rejected: remapping via $g_tpl (would keep legacy markup alive), rewriting pages as modern HTML screens (belongs to the screen modernization workflow).

This run reproduced the failure mechanism experimentally (removed one ported template → exact Smarty fatal + HTTP 500; restored → HTTP 200), then executed a per-page verification matrix with legacy-UI-equivalent arguments.

Regression suite: Suite 426 in tmp/TLU_Test_Cases.md.

• #637 — aside-menu report links carry no query args at all (asideMenu.php:79): every legacy report from the modernized menu 500s or renders empty.
• #638 — resultsTCAbsoluteLatest.php:313: count(null) TypeError when the plan has no builds.
• #604 — pre-existing: testAutomationSpec fatals inside specview.php regardless of templates.
