There is domain registration hosting plan based on a correctly configured LogicBoxes plug-in. When a customer tries to buy a domain in store using that hosting plan, any domain is shown as Unavailable, although whois link next to a domain name would say 'No match for "DOMAIN.TLD".' or "Not found: domain.tld".
LogicBoxes changed response structure in their API. Such behavior was classified as the software issue PBAS-30335 and will be fixed in future OBAS releases.
For 64-bit OS:
# rpm -Uhv hspc-plugin-dm-logicboxes-4.5.6-42.swsoft.x86_64.rpm # hspc-upgrade-manager --finish
For 32-bit OS:
# rpm -Uhv hspc-plugin-dm-logicboxes-4.5.6-42.swsoft.i386.rpm # hspc-upgrade-manager --finish
hspc-upgrade-manager --finish will cause OBAS downtime for several minutes.
