You are witnessing the first version of echan in all of its glory. This means there are still a lot of rough edges, (partially) broken features and possibly some missing features. Over time you will notice these problems will disappear, but our first goal was to get it up and running.
The old theme was alright, but had a lot of issues and rough edges. I switched it out for another theme which separates things a bit more clearly and makes echan more pleasant to use. It's still far from perfect and also has a lot of rough edges, but slowly but surely I'll be ironing those out. At least everything should be functional again!
You might need to do some hard refreshing (CTRL+SHIFT+F5 or whatever it is on your machine) for it to update your cache.
