problem with plugin Easy Dropdown Menu

[Aga C]

Hi,

I found an error Easy Dropdown Menu Error 500 Internal Server Error (I attach screenshot).

After verification, I can see that changes have occurred spontaneously in many projects in confluence. 

I'm asking for help in solving the problem.

Why is this error occurring? 

Thanks in advance.
