- Plesk 11.x for Linux
Bandwidth Limiting screen for Reseller/Client/Domain does not allow adjusting bandwidth usage and connections limits showing only "Unlimited".
This may happen if component "Bandwidth Limiter For Apache support (mod_bw)" is not installed.
Install component "Bandwidth Limiter For Apache support (mod_bw)" through Home → Updates screen in Parallels Plesk Panel or using command-line autoinstaller utility:
PRODUCT_ROOT_D/admin/sbin/autoinstaller --select-release-current --install-component mod-bw
