umbraco version 7.4.3 - Cannot open stylesheets in admin
Hi All,

Please help me to solve this.

Glad to know it has been solved! What kind of files? If we can reproduce this, we can create an issue on the issue tracker (or even submit a pull request so other people wont have this issue in the future).

Are you building custom trees? If not, my best guess is that you don't have all components. Also, check you don't have old dll's in the BIN folder.
Thanks Damiaan.
I resolved the issue. There were some non css files in that folder. It is working fine after removing those.
