I've upgraded from 3.6 to 4.0.5 but seem to be getting the following error on the "My Forum Topics" (forum.php?u=1) page from the My Account home page. I did have some minor customizations in a very few places so tried it with all the default scripts but still get this. Anyone else experienced this? Or can anyone else who has done the upgrade confirm yours is working correct?

Can anyone else who has done the upgrade confirm if yours is working correct?
 
Click on the "My Account" link then the "My Forum Topics" to verify.
 
The error messages appear at the very top of the page so it would be impossible to miss.

It appears that the forum > description block can not be included in the page layout for the forum topics page.
 
Would be nice if there were some sort of validation to help avoid this type of error so that only the appropriate blocks can be placed on a page.

Please open a Support ticket and inform the viart team about it.
 
They will fix the issue as soon as possible.
 
I dont use the forum section, so i cannot help.
