Your plugin section is a bit messed up mate.
<plugin config="@conf/plugin_aimbotdetector.xml" name="aimbotdetector" />
<plugin config="@conf/plugin_geowelcome.xml" name="geowelcome" />
<plugin config="@conf/plugin_awardsxlrstats.xml" name="awardsxlrstats" />
<plugin config="@conf/plugin_plugin_chat.xml" name="chat" />
Those should be in extplugins. Make sure you got them in the right folder as well as the plugin config files.
Should look more like this:
<!-- plugin order is important. Plugins that add new in-game commands all depend on the admin plugin. Make sure to have the admin plugin before them. -->
<plugin config="@conf/plugin_admin.xml" name="admin" />
<plugin config="@conf/plugin_spamcontrol.xml" name="spamcontrol" />
<plugin config="@conf/plugin_tk.xml" name="tk" />
<plugin config="@conf/plugin_stats.xml" name="stats" />
<plugin config="@conf/plugin_adv.xml" name="adv" />
<plugin config="@conf/plugin_status.xml" name="status" />
<plugin config="@conf/plugin_welcome.xml" name="welcome" />
<plugin config="@conf/plugin_pingwatch.xml" name="pingwatch" />
<!-- The punkbuster plugin was not installed since punkbuster is not supported or disabled. -->
<!-- The next plugins are external, 3rd party plugins and should reside in the external_dir. Example: -->
<plugin config="@conf/plugin_aimbotdetector.xml" name="aimbotdetector" />
<plugin config="@conf/plugin_geowelcome.xml" name="geowelcome" />
<plugin config="@conf/plugin_awardsxlrstats.xml" name="awardsxlrstats" />
<plugin config="@conf/plugin_plugin_chat.xml" name="chat" />
When using the geowelcome plugin you should also remove the standard welcome plugin, maybe go with the standard plugin for now since it's easier for starters.
Also <set name="log_level">22</set> is not really necessary, "9" should be enough.
<set name="rcon_ip">192.168.1.110</set>
B3 and Game Server are on the same box? Then it should be "127.0.0.1".
