Continued. when the default of the sandbox text is in there, i never see any errors. it's just that the plugin still does not cast. all other functions of the plugin seem to work.
here's the default sandbox text
trust_all_worlds = false -- change to true to trust all the worlds
trust_all_plugins = false -- change to true to trust all the plugins
warn_if_not_trusted = false -- change to true to show warnings
--[[
-- Lua initialization (sandbox) --> please read comments carefully.
-- Default initialization supplied with version 3.80.
Use this to create a "sandbox" for safe execution of non-trusted scripts.
If you only run your own scripts or plugins then you may not need this.
The code in this area is executed after each Lua script space is created
but before any of your scripts are done. This can be used to initialise things
(eg. load DLLs, load files, set up variables) or to disable things as shown below.
By setting a function name to nil you effectively make it unavailable.
You can remove some functions from a library rather than all of them, eg.
os.execute = nil -- no operating system calls
os.remove = nil -- no deleting files
os.rename = nil -- no renaming files
This script will automatically be replaced if you completely delete it from
the Global Preferences, and restart MUSHclient. To avoid this, leave a comment
in (if you don't want any further action taken).
