I have seen similar posts and have written to my host to enable system() and shell_exe() and they said they have enabled it.


Reply from the host :

We have provided the copy of php.ini file at the location /home/xxx/public_html/moodle/filter/tex/php.ini inside your account on the server and have enabled both the functions system() and shell_exec() for your account. You can check now.

Any suggestions/help will be appreciated.
