It looks like you might be missing a CSS file (causing the layout problem) and perhaps encountering a Javascript error (resulting in the TinyMCE problem). Check your access log for problematic response codes (like 404 for missing files, or 403 for permission problems).

I changed the file permissions and both of my problems seemed to be corrected.
But, still I cannot upload the custom CSS file. It says “No file uploaded or invalid file type!”.
MIME setting for my server seems to be ok as below,
I think there are a few other threads dealing with that issue. Start by searching for them, and if you can’t find a resolution, post a new topic with as much information as possible (e.g. your OJS version, what you’ve tried, and what the results were).
