Easy Chart Error in the Client page!

I used the easy chart in the context of a project. It works perfectly in the Run Mode (Designer). But it doesn’t work when launching the client page. May someone help me, please ?

Here is a picture showing what I’m talking about.

I’d like to mention that I used SQL Queries in that Easy Chart.

You probably need to turn on legacy query permissions in the project properties.


Thanks very much!
Yes. This was exactly the reason.
Feeling grateful.
