"JDownloads\Module\...\Helper\Error" not found - [Not reproducable]

[jazzbird]

After lots of frustration dealing with the "Column 'publish_down' cannot be null "
(which contrary to this thread appears to NOT be solved: https://www.jdownloads.com/forum/index.php?topic=13787.0)

I have completely deleted the previous version of jDownloads (including all database tables) and reinstalled a fresh copy of 4.0.5.

Now I get this:

An error has occurred.
0 Class "JDownloads\Module\JDownloadsAdminStats\Administrator\Helper\Error" not found

Jazzbird,
You are clearly having some 'challenges'.
It seems to me that there is something specific to you site that is causing the problems that you observe.

For me the problem  "Column 'publish_down' cannot be null " is no longer reproducible
Likewise none of my test sites have a problem with the the Statistics Admin Module
I am using standard Joomla templates (Cassiopeia for Front End and Atum foe Admin) - perhaps you are using another template?

But you are experiencing problems that seem to me to be specific to your site so something must be different.  Is it possible that I could access your site?  If so please send me a Private Message (they are secure) with super user rights so I can look. 

Presume you are running on PHP8 - could you advise which version please

Colin

Strange. Maybe he has changed the default module settings and use still not tested settings combinations?

But this is the main problem with many of our testers. It is usually not enough just to post the error. In addition, the most important information about the test environment including the settings is needed! And ideally how to reproduce the error, because that is the only way to find and fix it. 

[jazzbird]

Arno and Colin,

Thanks for your replies. Yes, the site is running on PHP 8. Also using Cassiopeia for the front end.

As for reproducing the error, I did not do much. Just completely uninstalled jDownloads (including the database), then reinstalled it and got the error I posted.

Colin, I will PM you some login details.

Strange!
Could you please enabled the debug option in your Joomla Global Config?
Try it then again and post here the complete error message (or send it me via PM). Thanks.

[jazzbird]

Sure:

Arno, is that what you were looking for?
I just installed 4.0.6 (after totally removing 4.0.5 as you recommend) and the problem is exactly the same.

[Arno]

Hi,
yes that it is. Thanks a lot, this should help me to find it. 

[Arno]

Hi,
please disable the view latest downloads option in module settings (see pic).
Try it then again. Repeat this with the other settings until the error no longer occurs.

Unfortunately, I still cannot reproduce the error message. 
Are there any categories and downloads in your download area? Or is everything still empty, with the exception of the default category for uncategorised?

[jazzbird]

Okay. I did what you said and the error disappeared after I disabled the "view featured tab."

But then I clicked on the 'jDownloads/Categories' menu and got this:

Would my problem be related to this issue that someone has had in the past?

[Arno]

Hi,
I am very surprised! The number of problems you have is unbelievable. 
But it is not possible for me to reproduce only one from this.

My questions:
What is your database version?
Are there any categories and downloads in your download area? Or is everything still empty, with the exception of the default category for uncategorised?
Do you have a possibility to test jDownloads on another website?

I'll have a look at the tips you posted later. Thanks for that.
