Our WordPress platform has been specifically designed to offer the best security, performance and reliability for WordPress.
As a result, we have specifically tuned firewall rules and layers of protection to help keep WordPress sites secure. As part of this protection, a small number of PHP functions have been disabled, as we’ve found that 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 highly unlikely 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.
