Change Maine PHP version thru PHP selector or PHP Switcher?

Hi, I just bought the the CWP7-Pro-Version.
The problem is when I use the PHP-Selector 2 New and try to install the PHP V7.3 it say red and then I push to install it but after about 30 minutes it is done it still it’s red and not installed.
Even when I use the PHP version Switcher 2 and try to select PHP version to PHP 7.3 it start I can see that on the CPU but after about 15 minutes it still PHP 5.6.
So what ever I do I can’t change to PHP 7.3

I also tried to change on the domain. There it looks like the PHP 7.3 is an alternative but when I change the domain to PHP 7.3 it add an .htaccess on the domain files with this in it
AddHandler application/x-httpd-php73 .php
But that gives me 500 internal error

What can be the problem?
Please anybody?

Chances are, that a script you are running on that domain requires a module that is not compiled into the php7.3.  Check /usr/local/apache/domlogs/(Domain).error.log to find out what the specific php error is, and post that.

Hi, the error file is very long with same info. But here is some of it.

check the required php version are already installed. You're using php selector.

It seems your server have issues with low ram memory.

Hi, on PHP selector it say (red) not installed on every version.
On PHP Info it say PHP 5.6.3.7
I have a small VPS with 1gb. And on PHP ini it say 128mb for each script.
Isn’t my memory enough?

I have sent you the login to my server before. Do you have time to take a look?

php 7 needs at-least 1.5 gb for the build.

Yea I had the same problem.  I had to shut down a lot of services like apache that were running.  Once I did that bam it was finished.
