Thank you for the reply.
I went to the mentioned directory (/usr/local/cwpsrv/htdocs/resources/conf/el8/)
I found 4 directories (php-fpm_selector , php_selector , php_switcher)
In each, there was a list of php versions .ini files (up to 8.3.ini), and (pre_run, external_modules) folders which also contains files related to each version.
I went through them all, creating symmetrical files for php 8.4 (8.4.4). It is now appearing in the CWP admin dashboard, when I check the version (8.4.4) and click on build, an empty log file of one line (Build successful), but on refreshing the page nothing is installed.
Are there other places need to be updated?
