yes resetting it will also remove your old courses and content , what we can do is you take wordpress export of your content , after we install the new v4 you can import to have your content back , but then you have set your menus , colors and widgets again.
Thanks a lot, I've seen that you have completed migrating the old files, there are some issues in the CSS as i think, isn't it? I will customize the home page soon, and i will let you know what we can do with these CSS errors.
Dear Anshuman Sahu,
I have tried hard to customize the homepage and some other pages, but everything looks messy, my web is not clean as the demo one, what should i do? i think there is a serious CSS error here.
