The options you change in the Theme Editor are global for everyone. They simply moved them from the ACP to the front end (where switching a setting updates the view in real time and you can see the change happen).

There's no API for that. Either IPS adds it or you make a custom application to implement the API yourself.

@Square Wheels Found it. I was able to reproduce what you're seeing after I enabled this setting in the Theme Editor: Page Layouts > Feature first post?

When this specific setting is enabled the post marked as solution is moved to the top.
Not sure if it's a bug or working as intended, though. IPS will have to answer this. 😋

Looks like you enabled only the Show on Member's profile? option.

To display the fields with topics/posts, enable also the Show with member's content submissions? option.

It's been renamed to "Featured Content", but it's still there: https://invisioncommunity.com/featured/

That part is not the description, but the forum rules. It only shows viewing the forum itself.

@Jim M It's a bug. The file was included in 5.0.1 after being imported from v4, but the class was not renamed to remove the underscore (which is not used in v5):
/** * 4.7.20 Beta 1 Upgrade Code */ class _Upgrade

You can restore the previous behavior by adding this custom CSS:
:is(.ipsFigure--contain, .ipsMasonry) .ipsFigure__main > :is(video, img) { object-fit: fill; }

Oddly enough, there is no way to disable it. The helpful button will always show as long a you're logged in, the post is not archived, and you're not the author. 🤷‍♂️

EDIT
Try adding this custom CSS to hide the button:
li.ipsEntry__controls__helpful { display: none; }

Have you already tried clearing the caches from ACP > Support?

Disable the permission for guests to use the Search module in ACP of the System application:


EDIT:
Looks like I had the tab open for a few minutes, but I never got the usual notification that there were new replies and the link to load them. It might be a v5 bug. 🤔

Fixed in 4.7.19.

It was fixed in 4.7.20 Beta 3 (or 4?).

If you don’t want to use the visual language editor, you can edit/translate the name from the ACP instead:

Maybe you have the prune logs setting disabled? Or some recurring error quickly filled up your table.
 
You can truncate the core_log table, or you can use this modification I made: https://invisionbyte.net/files/file/282-tb-delete-all-system-logs-button/
No need to mess with the database with it, you can easily delete all logs from ACP.

Which version are you using? That's a really old .htaccess file.
If you use the latest 4.7.19 version, re-download the latest .htaccess file from the ACP.

Oh, somehow I missed the previous reply.
 
You'd need to setup a redirect for the old forum folder and redirect all URLs starting with https://www.site.com/forum/* to https://www.site.com/*
Either use a .htaccess rule or leave an index.php file inside the forum folder with some redirect code.

It's a moderator permission in ACP:

 
Here's a link to the guide in case you need it:

Do you have any 3rd party applications or plugins installed? Most likely one of those is not compatible with PHP 8.1.

Since you don't remember the password, I assume the upgrade hasn't started yet. If so, you should be able to reset the password from the front end of the site. The error in your second screenshot is a known issue that will be fixed once you upgrade to 4.7.19:  
Just to clarify, version 4.7.19 is not out yet. IPS is working on it and it should be out soon.

You can ignore it.
 
It's a bug with a task that runs once a month and is fixed for the upcoming 4.7.19 version:

No, there is no way to avoid logging in again. Since the domain name changes, the old cookies won't work. There is no way around it.
The only way they may still work is if you move to a subdomain rather than a completely new domain.
