Blocking Items being created/placed with PEX

[xxdonavanxx]

So I have been trying to stop certain blocks being placed. Like the Energy Condesors. I know that you can stop the with PEX. I used the following to try and block creating it

/pex group default add -modifyworld.items.craft.126

But it still lets me make it. I made sure i was not in the "Owner" group or any other group other then default. This to my knowledge should not let them make Energy Condenser. I also did make sure i was not OP when I made the condenser. Any ideas?

I would appreciate any help if anyone knows more about PEX then me. I do not normally bump threads but this was near the bottom of the second page with no response.

Tekkit is mad because you banned a great and non-op item. All joking aside, I believe that when you are hosting a server, you have admin commands even if your rank is member or guest. Try asking a member or default to place one.

I host it on a different PC then the one i play on. I made sure i had OP off on myself and that i had taken myself off everything except the default group. Would removing the EE mod from the server still allow the server to be playable/join able? I only want to use this as a temporary fix until i can get banning items.
