Deprecation: #78668 - TypoScript option config.mainScript¶
See Issue #78668
The TypoScript option
config.mainScript allows to set the frontend entrypoint from "index.php" to something else, and is respected
when links are built, but not when e.g. previewing a page from the backend. This option has been marked as deprecated.
Setting this TypoScript option will trigger a deprecation log entry in the admin panel.
Any installation using this TypoScript option.
