I have this on online linux server and I'm getting errors for local files which is strange.
I guess he is trying to find .ini file of the user on?OnPlayerDisconnect but fails to process it somehow.
[debug] Server crashed while executing script.amx
[debug] AMX backtrace:
[debug] #0 00000035 in INI_AddToBuffer (INI:file=52, name[]=@00000000 "", data[]=@01d43894 "0000001600676554") at <unknown file>:0
[debug] #1 000147f0 in ?? (... <13 arguments>) at C:\Users\test\Desktop\sampserver\pawno\include\YSI\y_ini.inc:1076
[debug] #2 00000035 in public OnPlayerDisconnect () at <unknown file>:0
Also other problem that I have sometimes on other server is people get reconnected. Here is an example of the log:
Packet was modified, sent by id: *id*, ip: *ip*
