Our WordPress platform has been specifically designed to offer the best security, performance and reliability for WordPress.
Therefore, we have specifically tuned firewall rules and layers of protection to help keep WordPress sites secure. As part of this protection, many PHP functions have been disabled, as we've found they're often used for malicious purposes.
The following functions are disabled for security reasons:
exec
opcache_get_configuration
opcache_get_status
passthru
parse_ini_file
popen
proc_open
shell_exec
show_source
system
In our experience, it's unlikely that any of your plugins rely on any of the functions above. However, if you have a genuine use case for any of these functions, you can still host your WordPress site on our Linux platform.
