please make sure, you are running latest version of Reports module from https://github.com/DNNCom...DNN.Reports/releases

As Sebastian suggested... Always upgrade the third-party and custom extensions prior to upgrading. Upgrade any and all that have updates available. Then, upgrade DNN. (Always backup after each step, when possible and practical.)

As for the other errors, there's not a ton of context, except the unable to upgrade. Do follow with the tips offered in the error message you see in the upgrade/install wizard (provided it still occurs after following the previous advice.) If the file size is not the issue, using EVS could help you isolate any other potential installation issue it might have.

So, I have the same problem like Audun. Trying to upgrade DNN 7.2.1. to the latest version, DNN 9.8.0. I upgraded Reports module to the latest from Github (6.2.1.), tried first to install it after I upgraded DNN and before, like Will suggested, but the error is still there:

Any suggestions? Tested on DNN 9.2.0. too, but no changes..

 

It also breaks my whole page with Reports module on it.

 

Edit: Error prior to the last one is:

Did you follow the suggested upgrade path or did you go directly?

I am having the same issue with the DNN Events module. I upgraded the site to DNN 9.8.1 and follows the DNN recommended path. All other modules are working well. I installed the latest Events module through GitHub too.
I am getting this error and page loading with an error after a few hours. Once I remove the Event module from the page and place it on the same page, then it is working again. But page is giving an error after a few hours.

Please, can you advise?
Thank you!

Well, I tried with directly upgrade and with suggested path and it's the same.

What I did notice is that when I remove Reports module and add it as a new module, with completly the same settings and SQL query, it works and the page is just as it should be. I have few more Reports modules that are not working if I don't re-add them.

 

Edit: debug dll say:

 

[ERROR] DotNetNuke.Services.Exceptions.Exceptions - ~/Default.aspx?tabid=120&error=Object+reference+not+set+to+an+instance+of+an+object.&content=0
System.NullReferenceException: Object reference not set to an instance of an object.

Anyone, anything? 

I have so many Reports modules on site, it's not that practical to delete every one of them and then add them again..

Unfortunately, your error message is not concrete enough to guess the cause of the error.
You may compare values of database tables Modules, TabModules, ModuleSettings and TabModuleSettings of old report instances with newly added ones to determine differences. I would focus first on date and time values - maybe they are formatted differently, which may cause the issue, but this is just a guess.

So, I compared all tables in database from my old website and upgraded where there is some connection with Reports module and it appears that in my old database in dbo.ModuleSettings for SettingName "dnn_Reports_CreatedOn" SettingValue was "23.12.2020. 15:08:33" and in my database after DNN and Reports module upgrade SettingValue should be like "2020-12-23T15:08:33.8300965+01:00". I updated this setting in table for every single one Reports module on my website and there are no errors anymore.
