It has been long time since I faced this problem, in my CSS management I see the style sheet which is not used by my site, it is called personal style sheet, but anything in it is not applicable in the website and it is very short, I wonder why this is happening? and I can't even edit it or save any changes it is all static. and if i try to save it by clicking the "save" button and try to reload my website, the whole website design messes. Even if I clear the browsing data. my question is: 1: how can I edit this file "my.css"? 2: why what is shown in "my.css" is not functioning in the website?
below are screenshots: (a) My.css in Control Panel
