Guys Please help. I need it for my minecraft series recording on friday. First one to help me fix both the problems will get op rights on my server.

Check the worldguard config for lava flow and make sure it says "true" and not "false" or just post the config here and I'll go through it for you.

#
# WorldGuard's main configuration file
#
# This is the global configuration file. Anything placed into here will
# be applied to all worlds. However, each world has its own configuration
# file to allow you to replace most settings in here for that world only.
#
# About editing this file:
# - DO NOT USE TABS. You MUST use spaces or Bukkit will complain. If
# you use an editor like Notepad++ (recommended for Windows users), you
# must configure it to "replace tabs with spaces." In Notepad++, this can
# be changed in Settings > Preferences > Language Menu.
# - Don't get rid of the indents. They are indented so some entries are
# in categories (like "enforce-single-session" is in the "protection"
# category.
# - If you want to check the format of this file before putting it
# into WorldGuard, paste it into http://yaml-online-parser.appspot.com/
# and see if it gives "ERROR:".
# - Lines starting with # are comments and so they are ignored.

Can't really see anything wrong in the config. How about your modifyworld?

Essentials can also block those, check it's config

Code:

enable: false
itemRestrictions: false
informPlayers: false
whitelist: false
messages:
  whitelistMessage: You are not allowed to join this server. Goodbye!
  prohibitedItem: You have prohibited item "%s".
  permissionDenied: Sorry, you don't have enough permissions

Can't seem to find anything wrong here :/

It'll be essentials, since the default setting it for no lava flow and no flint and steel.

I will check as soon as I log onto my pc again.

Ah, I never use essentials since that seems to always be the plugin behind strange behaviors

Not really strange, it's doing exactly what it's supposed to I would bet. it's configured to try and protect people from griefers as much as possible, hence blocking lava flow and flint by default

It all looks ok
