i tried that and its not working and it only happens in Chrome.

I’m sorry, I don’t have anything to add to the list of articles above. Each article approaches a slightly different cause of the error. I suggest you try them all. Just because it only happens in Chrome doesn’t mean its an incompatibility in Chrome. There are different versions of that same error message, per the above articles. It means one thing when they are surrounded in a red box and another when in an orange box. One is about “suspected spam”. It explains the source of it.
That is all I know about it so I can’t assist you further, sorry.
