Re: Errors in installing moodle 2.7.3 on Centos 6.5

Now I get this error :
########
Error : Database Driver problem detected.
PHP has not properly configured with the Mysqli extension for it to communicate with MySQL. .....
########

And also the last lines of apache error log is like this:

I assume it is the uncompatibility of Moodle 2.7.3 with PHP 5.6.3. Am I right?
