I am facing an error as per below at admin panel login.

“ERROR: Cookies are blocked due to unexpected output.”

I’ve tried several solutions like,

1. Log checking (No logs are showing in log file)
2. Resolve header already sent issue (Not getting this error at all).
3. Check incomplete ‘php tag‘, removing white spaces etc (Have already checked both).

We have re-solve above 3 things but still the issue is there.

Would anyone please check this and help me on this ?
