Is it possible to downgrade from Moodle 3.1 to Moodle 3.04? and How?

RK, If you google the phrase "downgrading Moodle" you will find your answer in a range of forum posts. I think it is No. I won't ask if you did a backup when you upgraded.
I do notice in your other post that I replied to that you are using Lambda theme and that your problem is solved with Clean. You did not answer the other question I asked about errors. BUT: (chances are) changing your theme will be probably easier than any other options or getting the folks who made Lambda to fix it.
And PS: just in case you didn't know, [see https://newrepublic.com/article/117390/netiquette-capitalization-how-caps-became-code-yelling caps], in internet communication channels, all cap;itals is generally regarded as yelling. I think it may be the same around here, I'm not sure.
