5.4. to 6.0 create feed error message
After upgrading 5.4 to 6.0 I get the attached error message
(could have been there in 5.4 but I don't remember :-))
I had forums deactived in 6.0 but reactivating did not make any difference (I would not have know how these two were releated) and since I do not have a forum I did not do the last upgrade instruction part about forums.
Would it be possible to check the System.config file to see if the Forums module was properly upgraded and is on version 6 as well?
You can try the following on a backup copy of the website: From the modules menu, disable the Forums module, after that uninstall it from the same. Once it is uninstalled, restart the application, install it, and restart it again. If the issue persist try the same for the Feeds and Notifications module.
If the problem persist, we will need to take a look at the project locally.
Upgraded to 6.0.4200 and the issue is gone.
