Help with running tekkit

[lemons]

Im starting a new 24/7 tekkit server but I cant really get logblock to work and world guard to work. Logblock dosent seem to record all the data at all and I set it up correctly and double check it twice but nothing. It runs it just dosent record. And the problem with world guard is that I made a zone to protect spawn but you can place blocks but not destroy theme. And the last problem is that when I try to disable Nukes it wont disable it.

I would also like to know if there is a way I can disable all explosives since they are a major grief tool at time.

I would appreciate all the help and advise
