Hi Maverick:

Situation reported here:

https://shondalai.com/topic/cannot-access-protected-property-joomlacmsmenumenuitemparams/

Also happens with Community Surveys.  

Letting you know so you can update as you did with CA the corresponding file(s).

I fixed these issues with the deprecated APIs. Can you please update v5.3.3 and check if the issues are solved?

Thanks
