Hallo Vinod,
here is my site url

https://dberedimas.sites.sch.gr/

As i said, when i am de-activating the plugin, and the next minute i activating again,
all comes back to normal.
In the next step, if i click from the website the live modulator, problem appears again and remains and i must start from the beggining.
Right now i left with the problem, so you can safely inspect it.

many thanks for your time
Jim
