Different problems in different computers

[firedrop]

Hi All,

I have a problem with one of the functions that I am using in my website. The function basically forth staff to shift on/off.

I test it into three cmputers that they show me different errors.

The first computer it works fine unless if there isn't any row in the database. it displays an error when I try to shift on. The error is:

Warning: Cannot modify header information - headers already sent by (output started at C:\Program Files\xampp\htdocs\CBDHealthSpa\test.php:130) in C:\Program Files\xampp\htdocs\CBDHealthSpa\test.php on line 147

The second computer it display a debug error any time i try to shift on/off. The debug it attached into the message.

The third computer it works find for the first time when I shift on/off. The second time or even more it dsipaly the same debug error.

I have attached a zip file that contains the php code and a screen shot of the debug error.

Any one can help me with this.

Regards,
firedrop

Unless you use output buffering, you can only send headers (e.g. using the header() function) before any output is sent. On line 130, you print out some HTML code, thus causing output to be sent before the header() call.
