My apologies for taking of your time. I had done a major stupid. I always take a fresh copy of my site and place it in a separate folder to test new mods to make sure I don't break the live one. While looking again at the configure.php files, I realised that I had forgotten to rename the store folder. So the errors were getting logged in the live store folder.
and if it can help anyone else with a different default language, I installed it again while having the default different language installed and it wasn't an issue at all. So no need to remove the language etc...
My sincere apologies, all is well now.
