Hi. I have installed the Apache webserver on Linux CentOS. I received the above error in server logs. It is kind of you if help me to fix it.
You face this error because the php-json package is not installed. to install the package, run:
yum install php-json
Then, you need to restart httpd. So, type:
systemctl restart httpd
Now, the error should be solved. But let me know of any probable issues.
