Cannot modify user groups or add new groups

[Neej]

So I am currently setting up a 4.0 forum which has a database from vbulletin5_connect converted to 3.4.8 and then upgraded to 4.0

I have come across two issues, another which I posted a thread about earlier today in which I was not able to add content blocks. https://community.invisionpower.com/topic/419605-cannot-create-custom-blocks-in-ip-pages-40/

I have now come across a new issue in AdminCP when I go to Member Groups and try edit a member group or add a new group. I get "EX1048 Something went wrong. Please try again. "

Here is a server log

Does this mean my database might have errors from the conversion? Anyone know how to fix it

 

Thanks.

Issue resolved, there were some errors in our database which have been fixed up manually.
