Once you install the mod you have to put it in your mods folder. Open file manager, type %appdata% in the search bar, click ".minecraft" and then put the mod in the "mods" folder.
What plugin do you have?
Does it have a config you have to edit?
Does the plugin show up in /plugins?
Are you on the correct version?
Please answer these questions and I can help you.
There are two options here:
1. This one is much more likely. You may have a modification on your client used to "autotip" on servers such as Hypixel, and it's trying to tip
2. Someone somehow got access to commands and is making you say this stuff.
Hey,
This bug has been reported to Minehut via the proper channels (https://github.com/Minehut/Meta/issues/960). We are currently waiting on a response from Minehut.
You have to put in your mods folder. Get there by going to your file manager, typing "%appdata%" in the search bar, click .minecraft, and find "mods". Put the mod in that folder
This looks great. Just a tip: Try to be consistent with function names. You have "VoucherUse" and "voucherGive", 1 CamelCase and the other not, and then you have voucher at the end of "setItemVoucher" and "getItemVoucher".
