Issue

Cannot enable the JSON extension in CloudLinux PHP Selector

Environment

• PHP Selector

Solution

1. Validate the alt-php7x-common package and check if the /opt/alt/php7x/etc/php.d.all/json.ini was modified manually, e.g.:

~# rpm -V alt-php74-common
S.5...GT.  c /opt/alt/php74/etc/php.d.all/json.ini

S.5....T.  c /opt/alt/php74/etc/php.d/default.ini
S.5....T.  c /opt/alt/php74/etc/php.ini

2. Make sure the file looks as follows:

~# cat /opt/alt/php74/etc/php.d.all/json.ini
; Enable json extension module
extension=json.so

Cause

 The /opt/alt/php7x/etc/php.d.all/json.ini was modified manually on your server.
