Will not work for me!
ok loaded the mod with no issues.  Granted myself permission and got the proper response.  type /stackall 6000 in chat and nothing happens.  Nothing changes.  Help please.

Pewpew
Did you check your oxide/logs for errors?
in full disclosure I am new to this.  I do not know where to check those logs.  I have managed to get 3 other mods to work but these last 2 (which are the most importent to me)  are fighting me.

Merged post

Ok found them.  No errors that i see.

Merged post

ok now that I have gone over it there are several errors but I dont know what to do.
For Stack Size Controller, looks like your config file for the plugin is invalid and should be fixed or reset.
I find it is far easier to edit the stack size by using the config.json file and going through all the items one by one, I cut and paste the whole thing into a
"new text file" on my desktop as the server host page closes down after a short time which can be frustrating, I go through the list and change what I need then open the config.json file and delete all text and copy (changed) list back again, I retain the "new text file" till after I reload plugin just in case i have stuffed anything up :)
You have to remember that some items will NOT stack above default that is game set, Riot helmets for instance will not stack, most weapons will not stack, bear traps no longer stack and most annoying is the red/green/blue cards will not stack,

So the best thing to do is remove config/data/lang files for the plugin then remove plugin and reinstall it, then try the steps above.
Anyway have fun with it
