This error usually occurs when there is output on the page before the session is opened. in IE, there is no output, but in firefox, before the formal page output, there is a garbled byte. This garbled code is the cause of the error (it was output before the session ).
Solution: Find the file with an error prompt, download it, open it with the editor (the latest editplus version is recommended), copy the code, delete the file, and recreate a new file, copy the code just now, when saving files, must be saved into a UTF-8, upload overwrite the original file, should be good.
