i found a bug while updating theme

So. I had theme responsive version 4.7
Then I put version 5.0 in the same folder than before. The style.css stopped working. I tried version 5.2 today, and still the same problem.
Then I renamed the folder to something else, and bingo! The old version configurations conflicted with new version, in a way that broke the style.css from reading and maybe something else got broken in the process.

So, mark, something is roth in the denamark kindgom. If you find out what it is, please let me know.

For now I will have to annotate eeeeverything i customized on version 4.7 and put back in 5.2 and well this is somewhat time consuming and I think this is a non wanted behavior, right ?

If you find a fix, please let me know 🙂
thanks
