I installed your phpstudy windows version. My system is win7. Let’s take a look at the picture first:

I added a website and the directory is through " The directory selected by the "Open" button is actually E:\program\php\tp5\public. When I access the web page, I find that \t has become a tab character, causing the real page to not be found. The following is my error.log The log seen in:

2018/09/07 22:16:48 [crit] 23228#22920: *2 CreateFile() "E:\program\php p5\public/favicon.ico" failed (123: The filename, directory name, or volume label syntax is incorrect)

Hope it can be improved! Thanks!
