Question Modules assigned to forum page dont show

Thank you for the clarification.
Can you tell me which types can be fixed automatically if I provide you with the list?
Returning to the original and important issue 

I think the Rocketheme Supra is written for Bootstrap 5. If so, it will not work, because we don't have a Bootstrap 5 capable template for Kunena

i asked Rockettheme and they replied that the Supra version I am using on Joomla 3 is bootstrap 2.3.2 

This leaves these issues still unresolved
   
2. The modules I assigned to the menu item do not show
3. The layout is not formatted the search button is covered or overlapped in z-index or padding issue
4. In the tools section using diagnostics I see about 100 issues reported in dev  site and almost the same in live site

Thank you

In principle, these can be fixed if there is a "Repair" button next to this message.
However, this can also lead to the next message.
Example:
If you remove an orphaned message, the next message "messageBodyMissingMessage" may appear. This must then be fixed as well.
I don't know your errors and I don't know all the errors that are possible. 
First recount the statistics and see if there are fewer messages.
In my tests I never had problems with this option, but something can always happen.

The modules I assigned to the menu item do not show

Please check the module positions again, they are not the same for all templates. And also in the module itself, whether this is assigned to all menu items.

The layout is not formatted the search button is covered or overlapped in z-index or padding issue

In this case, Crypsis should work. But you can try in the Crypsis setting "Load bootstrap css = Yes".
Crypsis = bootstrap 2
Crypsisb3 = bootstrap 3
Crypsisb4 = bootstrap 4

Edit:
I have found the issue.
It is because you must select all the sub menu and the parent menu item in the module assignments tab
Then unpublish the module instance in the outline if you dont want it to show two or pick either module assignment or module instance in the outline

Hopefully this will help others in the future

Now the remaining questions are for fixing the errors in the list below and the search bar overlapping the button behind it?
for search field 
#kunena .layout .search-query {
    width: auto;
    margin-top: 30px;
}
Of for button 
.form-search .input-append .btn {
    /* -webkit-border-radius: 0 14px 14px 0; */
    -moz-border-radius: 0 14px 14px 0;
    border-radius: 3px;
    margin: 10px;
    min-width: 50px;
}
Change the tooltip to say click the button this needs work or remove the button completely with the following CSS

.form-search .input-append .btn {
    /* -webkit-border-radius: 0 14px 14px 0; */
    -moz-border-radius: 0 14px 14px 0;
    border-radius: 3px;
    margin: 10px;
    min-width: 50px;
    display: none;
}


This is the list

I verified with Rockettheme the module is assigned properly
I set the Crypsis setting "Load bootstrap css = Yes" as requested the result was minor spacing but overlap and still no modules

Thank you

Not much can happen there. Most of them are orphaned attachments. How you get orphaned attachments you can test it. Orphaned attachments also are displayed in the diagnostic, when users upload attachments sloppy. It means, that the user had uses the browser back button and again the forwards button before save. Kunena register this as abort and enter no message ID for this image.
Or a user do not use the cancel button if he not send after image upload his message. All this attachments get the mesid 0 in the table #__kunena_attachments.
You can see in the frontend in the message "You do not have permissions to access this page." instead of this image.

The rest are just some messages. I do not see any problem.

As for Crypsis, does it work with the Joomla template Protostar?

Thank you for the clarification on the fixes.

No I tried another template and the button is hidden under the search field
It doesnt make sense anyway because the mouseover modal info popup doest explain you need to click the button and the button itself doesnt have any words on it so nobody would no what to do in most cases.
I would rather takeaway the button and improve the wording in the popup modal.
Do you anyway to do any of those options?

 

That was not what I wanted to know. With Protostar it is more meaningful. I would have to see what you mean, a link to your forum would be helpful.
