Fixing MultiTV SQL Errors After Upgrading an Older Evolution CMS Site

Upgrade-related MultiTV failures often look dramatic because they surface as SQL syntax errors inside the manager. In many cases the root cause is much simpler: unresolved placeholders such as [+PREFIX+], outdated include files, or old custom TV definitions that no longer match the upgraded runtime.

What to inspect

• the TV input configuration and included PHP file paths
• placeholder expansion in SQL fragments
• whether the custom input file expects an older manager or parser context

After upgrades, custom TVs deserve the same review attention as snippets and plugins. They often carry hidden assumptions from the older build.
