Deploying Codeigniter 4 Website on LAN server

That looks like the end part of the index.php file.

Have you made any changes to the index.php file that would break the PHP? such as a punctuation character?

On my system running 4.1.3, that is part of line 27, so it seems that up until line 27 all was fine, then it had a problem.

Can you check that and if it all looks good, show the full index.php file here.
