The plugin does work well, however it print this error pretty often in the console
Code:
L 05/14/2019 - 19:20:43: [SM] Exception reported: Array index out-of-bounds (index 64, limit 55)
L 05/14/2019 - 19:20:43: [SM] Blaming: weapon_restrict.smx

L 05/14/2019 - 19:20:43: [SM] [1] Line 202, restrictinc/events.sp::CS_OnBuyCommand
edit: got it fixed with 1.9
