500 error on admin gui of cwppro after update

Hello when I try to access the cwp from the link https://167.86.xx.xxx:2087/ gives me the error 500.
I looked inside the log error inside the folder and the message is the following:

I suspect something went wrong in the update.

Also if I go up

/scripts/update_cwp

The answer in terminal is:

update_cwp: line 1: /usr/local/cwp/php54/bin/php: No such file or directory

And actually inside /usr/local/cwp/ there is only version 7.1

If I try to change version by modifying the first line it gives me an encoding error.

At this point I tried them all from your forum, I would need your assistance.

you will need to contact cwp support for that, if that is centos 6 32bit then you will need to migrate to a new OS.
