Hi,

proc_open() is an internal function of PHP since php 4.3.0 and is part of core PHP, so does not depend on any extension
See proc_open

I do not understand why there is this PHP Fatal error: Uncaught Error: Call to undefined function proc_open().

Maybe because the installation and/or the update of Wampserver have not been done "as administrator" or because you are not up to date in the VC++ redistributables.

- Verify that all VC ++ packages are installed and with the latest versions.
To do this, use the tool:
Checks VC++ packages installed
Do not use a previously loaded tool. Make a new download to make sure you are using the correct version.
To download missing packages, do not rely on Microsoft links, they are not reliable, download packages on http://wampserver.aviatechno.net in section Visual C++ Redistribuable Packages
Do not forget that if you have a 64 bit Windows, you must install both 32 and 64 bit versions of each package.
You must install each package "as an administrator", so right-click the exe file and then run as Administrator.
