Re: Flexi tasks are not working.

Have you run other workflows using FlexiTask recently?  You might try a few steps to isolate this a bit...need to determine if there is a general problem with Workflow or is it really isolated just to Flexi-task actions.  The text of the error message is specific to task actions, but I wonder if other actions will work.

If you replace the FlexiTask some other simple action like "Log to History", will it work without error?  I would test with various other actions to see how widespread the problem is.

Do you have other workflows working with in other sites?

Re: Flexi tasks are not working.

Have you tried using Flexitask in another workflow on a different sub-site or site collection?  You might need to open a support request on this or re-install Nintex Workflow.
