**Your problem**  
My problem is: Im trying to install the script in a sub folder(v2) but i’m unable to install the script, it says _" The site is currently offline due to encountering an error. If the problem persists, please contact the system administrator."_ after the 2nd Step

These errors are showing in the log:
