The error is due to a known issue and it will be fixed in the next official update of the Denodo Platform. Meanwhile as a workaround, I would try the following steps:
1. Navigate to the VQL tab of the view for which you want to disable the execution plan.
1. Copy the entire VQL and open the *Tools* → *VQL Shell*.
1. Past the copied VQL and remove the *CONTEXT* clause part of the query at the end, you should see something like below:
* *CONTEXT (QUERYPLAN = ....*
1. Then, execute the modified VQL (after performing the ***#3***) which will replace the existing view without any execution plan.
Hope this helps!
