Problems With Installation: "Warning: Unknown: POST Content-Length...."

Hi, i'm getting the current warnings on the installation process, and i would like to have some help.

Warning: Unknown: POST Content-Length of 144 bytes exceeds the limit of -1149239296 bytes in Unknown on line 0

Warning: Cannot modify header information - headers already sent in Unknown on line 0

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent in C:\xampp\htdocs\support\setup\install.php on line 27

These are the following warnings i'm getting, i'm trying to install it on Windows 7 Localhost.
Please if anyone can help me.

Thanks for all.


  • Did you follow the directions for installation?

    It sounds like your webserver is sending headers, or that you are trying to wrap OST using your own script.
  • Hi,

    try the following: Look into your php.ini and search for an entry "post_max_size". If you have an value there like "= 128MB" or something similiar, change this to "=128M" (and possibly restart your Apache or whatever you are using on your localhost)
