@ICostaEx

Code:

int price = Integer.parseInt(event.getLine(1).split(":")[0]);

Bam! It has a color code in it which is messing up your parsing.

 

@ICostaEx

Or http://jd.bukkit.org/rb/apidocs/org/bukkit/ChatColor.html#stripColor(java.lang.String)

 

I see no Color code in that line nor a line near it... this plugin worked with 1.7.10...

 

@ICostaEx getLine(int) returns a line. That line has a color code. Refer to the exception that was thrown if you don't believe me

 

As @Skionz (Sorry for qouting if you don't like it) said:

Code:

int price = Integer.parseInt(event.getLine(1).split(":")[0]);

Try doing something like this if you still get the error tho:

Code:

String line1 = ChatColor.stripColor(event.getLine(1));
int price = Integer.parseInt(line1.split(":")[0]);
