Hi,

im getting errors on trying to install. im using Plesk hosting panel https://www.plesk.com/ 

i do have my open_basedir setup like this : {WEBSPACEROOT}{/}{:}{TMP}{/}{:}{/}var{/}lib{/}php{/}session{/} 
i did check here and its a valid way of having it: https://support.plesk.com/hc/en-us/articles/115000278993-Domain-does-not-work-open-basedir-restriction-in-effect

i do have the path /var/lib/php/sessions in my open_basedir but your script is saying its not...
Note:(i removed my domain and replaced with DOMAIN.COM in the errors:
