Lock topic - no one can reply to the topic anymore.
Pin topic - appears at the top of the forum.
Hide - hides the post/topic from non-staff without permission.
Feature - Can add our feature block on a page and the topic will show up there. Can be topics you want to highlight for whatever reason. 

Looks like the FURLs were customized in some manner as the system is not allowing an update of these to the new "Events" scheme. I would advise using the "Revert" button in ACP -> System -> Advanced Configuration -> Friendly URLs to revert this and it should work again:

As you're using CloudFlare, you will want to enable "Trust IP addresses provided by proxies?" in ACP -> System -> Advanced Configuration. That will prevent CloudFlare's IP addresses from being used as the user's and creating a false positive in the Spam Defense system.

Are the permissions on the button setup correctly for your use? You can find this in ACP -> Customization -> Toolbars -> click the stock replies button.
If so, could you please provide a user's display name or ID that is having issues?

Split this into a new topic for you 🙂 .
Depends all what you're attempting to do. If you want to add/modify CSS, using the custom.css file in your theme would be advised. If you want to modify HTML in your theme, that can be done as well. For more info on that, can go to:  https://invisioncommunity.com/4guides/themes-and-customizations/getting-started-with-themes_324/introduction-to-themes-r108/
There is also Pages where you can create a whole new page based on your custom HTML/CSS. Which you can read about here: https://invisioncommunity.com/4guides/suite-applications/pages/core-concepts/introduction-to-pages-r149/
However, customizations, such as all the above are outside our scope of support.

Our "Powered by Invision Community" is required per our license agreement. There is a one-time removal fee which you can pay for.
The theme by line, you will need to contact your theme's author. That is not inserted by our core software.

If you have made quite a lot of subsequent requests to our server for this, you might be temporarily blocked. I would suggest give it 15 min and try again.

Please switch to an unmodified theme and test again. If that does not resolve the error, please disable all third party applications and plugins. Odds are it’s something there. 

If you have any UI, suggestions you're welcome to provide those in our Feature Suggestion forum. In short though, version 4 is radically different and technologically more sound with data than version 3 was so you should not have to do these recount tools or clear tools unless there is a specific need. If you are encountering an issue or have a question, it may be better for us to investigate what is happening here.

You will want to setup your Achievement rules, ranks, etc... then use the rebuild button in ACP -> Members -> Achievements -> Settings. 

Pretty sure Twitter disabled the old v1 of their login API so you can't create a new application on the old version. It is only the new version now. This is something which we are working to upgrade towards.

You wouldn't need to remove them for the upgrade to happen. You would just need to manually upgrade the template afterwards.

You will want to disable all third party applications/plugins and switch to an unmodified theme. These are most often related to one of these being out of date or not compatible with the release you're on so eliminating this is the first step.

You would only use one or the other. Mapbox does not have address prediction.

If you want all the information of the gallery photo, I would just have them post the link to the gallery photo, cut out the middleman. As there is no way to embed all the information of the gallery photo in forums. You can insert a gallery image, but it will not contain all the data in Gallery.
Of course, I do not know the purpose of the forum in this context but what are you gaining with the forum topic? Gallery has the ability for users to comment directly on the gallery album/photo. Having your users go directly to the gallery album or photo may be the best way to curve any confusion and any duplication of data. Then in the forum, if you do need to add a relationship between a forum topic and gallery album/image, just post the gallery album or photo's URL.

Anything in the sidebar would be moved to the bottom in the responsive layout. You will need to put your block in the top block location (see screenshot), if you wish for it to remain at the top on mobile.

You would want to check what the 500 Internal Server Error is and check with your hosting provider/server administrator to resolve any server issues. Then pass any issues with our software to us here. If you're using any third-party widgets on the Dashboard, you'll want to disable those and see if that helps.

Sorry, only the latest release is provided via our Client Area as this is the most stable and secure version of our software. If you require previous versions, we always recommend downloading them and storing them yourself while they are available.

Go to your Profile -> Edit Profile 🙂 . It's a custom profile field.

The only option in version 4 would be what version 3 called "quick reply". It is the full editor, however.

You can do this for a whole group or just for a first few posts for a group in ACP -> Members -> Groups -> edit group -> Content tab -> Require approval before content shows? (ensure you have "Bypass content moderation" disabled)

That would indicate that the template there is not compatible with the latest release and you'll need to work with the author to ensure it is compatible.

Sorry, there is currently not an automatic notification system to the reporter based on what is happening with the reported content in the default software. You can certainly suggest this in our official Feature Suggestion forum.

Author would be the author of the content which is being reported. Whereas, the reporter would be the individual who reported it.

I'm afraid, this would be a new feature, not a fix as the system is currently designed not to do this. You can certainly suggest it by going to our official Feature Suggestion forum.
