I was in very critical need to fix. I google for almost 2 hours & tried lot things to fix it. But it didn't. Hence decided to post the question.
I have written very clear in my question,what links I followed, what could have caused the issue & PLUS highlighted that its very crucial.
But few people on this community are more interesting in down-voting,suggesting useless suggestion instead of finding the way to fix it.
Steps that fixed for me
- Disabled the Optimization for a while
- Navigated to sites/default/files, deleted the default .htaccess
- Uploaded the new .htaccess
- Cleared the Cache
- ReEnabled the Optimization
Thats it. It fixed the issue
