[Tiki-users] Installation problems - tiki-check.php fails

Hi.

I'm installing a new Tiki 27.0 from the tarball. The previous version is 26,
with an already existing database. (I've done so via Git before, which
worked.) I've installed PHP 8.2 and set it as the version to be used by
tiki. 

When calling "sh setup.sh" (as root), I chose "f" (fix file & directory
permissions (classic default)), "and then "x". That's the default. 

When I call tiki-check.php, I get this error in the browser:

Fatal error: Uncaught Error: Call to undefined function
smarty_function_ticket() in /var/www/html/tiki/tiki-check.php:2990 Stack
trace: #0 {main} thrown in /var/www/html/tiki/tiki-check.php on line 2990

It's the same as with "b" first. 

However, the tiki-install.php page sort of works. Except for these warnings:

Warning :20231008_fix_primary_key_issues_on_several_tables_tiki, Incorrect

In the last step of the installer, there's this at the bottom:

"Oops. You need to make sure client charset and database encoding are forced
to UTF-8. Reset the database connection to continue."

And I get an ugly blue bubble with the text "Skip to main content" on every
page, to the top left.

There must be something broken...

Cheers,
