Error: Lua error: Cannot create process: proc_open is not available. Check PHP's "disable_functions"

So basicly i using a midiawiki plugin called Scribunto however i cant use it as i get this error.
Error: Lua error: Cannot create process: proc_open is not available. Check PHP’s “disable_functions” configuration directive.
After a bit of Research i found out why

I was hoping this could be sorted for me

If not it not a problem but i will have to find a plan B or another host
Thx

Command line access is blocked on InfinityFree, so proc_open and other functions like it cannot be used here.

And no, we can’t install a custom PHP extension for you. We can’t do custom server settings and modules for free hosting. Most web hosting providers don’t allow/support this, so you may have to get a VPS for this.

Ok thank you i will try find another way round it
