For the 1st error, try setting the HTML Character Set to UTF-8 in the Language Manager in AdminCP.

For the 2nd error, enable debug mode to see the detailed PHP error stack trace.

You're using PHP 8.3? vB5 does not support PHP 8.3. Please see Wayne's post here:

Try clearing system cache before doing the upgrade. And if you are using any type of caching system, turn it off.

Did you follow my first suggestion in post #2 where I said to change the HTML Character Set to UTF-8?

Use the tools.php in the "do_not-Upload" folder in the VB 6 package
Then reset your language.
