Blocked a frame in Google Chrome

[hooker007]

I use Dklab_Realplexor and lately I have been getting an error in Google Chrome: Failed to load resource: net::ERR_BLOCKED_BY_CLIENT ?identifier=SCRIPT&0:61 Uncaught DOMException: Failed to read a named property 'Dklab_Realplexor_Loader' from 'Window': Blocked a frame with origin "https://example.com" from accessing a cross-origin frame.
How can I fix this error?
