It seems that there's an issue with one of the fields on the "Content" Tab. Switch the tab to see the highlighted field and it's error.

My guess is the forms app because following hook is being mentioned in the error stack form_hook_formRegisterController

I'm really sorry for the confusion here.
@Jim M just shared some further details with me and it looks like a legit issue, which I have logged to our bug tracker.

That’s the IP. Download app in combination with commerce.
You’ll also need commerce if you want to allow your members to sell the items.

I'm working on the nightowl ticket right now.
 
Edit: It's an issue with the "neviewpasswordonstandardlogin" plugin

It’s available while editing a forum.
 

This was patched today. Please visit your ACP-System section and follow the instructions to apply the patch.

We have moved this to the integrations section. ( ACP-System-Integrations )

IMO it's fine to show it while editing, I mean what if it was created anonymous by accident or if something shouldn't be anonymous anymore, but I would prefer if it would be an extra setting or a moderator permission to control who's able to toggle the anonymous flag while editing existing content.
 
That said, I have brought this up internally.

Thanks.
This should be fixed in our November release:) 

Apologies, this was the wrong code.
 
That's the correct one:
{{if \IPS\Dispatcher::i()->application->directory == 'blog'}} Your code to show only inside blogs {{endif}}  

This means the internal IPS Advertisement System ( https://invisioncommunity.com/4guides/monetization/internal-advertising-r57/ )
 

Set the type to "Other/Manual" and then use following code:
<?php $options = ['fa-angle-up' => '<i class="fa fa-angle-up"></i>', 'fa-chevron-up' => '<i class="fa fa-chevron-up"></i>', 'fa-window-close' => '<i class="fa fa-window-close"></i>']; return new \IPS\Helpers\Form\Radio("core_theme_setting_title_{$row['sc_id']}", $value, FALSE, array( 'options' => $options, 'parse' => "raw" ), NULL, NULL, NULL, 'theme_setting_' . $row['sc_key']); Result:


 
You could also use the IPS\Helpers\Form\Custom form field type which allows you to literally customize the whole output...
 
 

Zapier should show all available variables once you click into the editor

 

Check your menu manager in the ACP and make sure that the " My Activity Streams Menu" is placed in your menu! 

That's a per ad setting appearing on the form while creating/editing the advertisement under ACP => System => Advertisements.
 

Please make sure that all your dev files are up2date!
 
And if they are, make sure that none of your 3rd party apps/plugins is accessing the deprecated IPS\Application::$ipsApps variable, which was mentioned here:
 

Just to follow up on this, this was caused by a bug which was fixed for an upcoming release.

ACP => System => Postings. The setting is called "Post Before Registering"
Hint: You can always use our ACP live search to find such stuff;) 

We have announced the feature with some further information here

You could report the file

I can confirm that we have a ticket for this and I'm actually looking at your issue.

This was a valid bug in our software, which I've just fixed for an upcoming release.
