Have a look at the Upgrading section of the following guide:

Sorry, I don't see Marketplace menu

 

Sorry, I don't see Marketplace menu

You can skip that part as it's irrelevant to upgrading your forum. As a fyi, the Marketplace has been removed, hence why you don't see it. That said, the section that you need to read up on how to upgrade your forum at the link I posted above is called: Manual Upgrade.

After migrate I see error under PHP 8.4

PHP Fatal error: Cannot redeclare function mb_ucfirst() in /var/www/www-root/data/www/***/init.php(1619)

How I can fix it ?

 

After migrate I see error under PHP 8.4

Can you downgrade the php version to 8.3. and see if that error will still occur? What about third party stuff, are there any present? One more question, did you actually run the upgrader? I'm asking because I've seen quite several topics here on the upgrade when users didn't run the upgrade at all after uploading the files from the new version.

You would need to use PHP 8.3. I believe that is the cause here

@Marc Yeah, downgrading to PHP 8.3 will work because PHP includes natively the function starting from PHP 8.4.

In any case this previous bug report is now a proper bug and not just feedback:

Thank you, the transition to version 5 is complete. But your transition system has some shortcomings.

1. When upgrading the PHP version in the server control panel, you need to install instead of "PHP as an Apache module" - CGI! Otherwise, IPB will not work correctly.

2. After the upgrade, the "Pages" icon disappears in the Administrative panel for other languages. How can this be fixed?

it should work on php 8.4 without problem too 🤔

You would need to check within your language pack and correct the relevant translation. We are unable to assist with 3rd party translations, but take a look at keys beginning with "menutab__", as they are what control the icons that are picked up. In your case, you are probably translating menutab__cms which you shouldnt be unless you are intentionally trying to change the icons
