"uninitialized constant PBEffects::EchoedVoice" error at start of battle

Hi, hope I am posting this in the right Thread
I am getting this error popping up at the moment:


It does so when walking on a patch of grass when a wild battle is triggered.
I had a look in the scripts section but I don't know what the issue is... and so don't know what I need to change to fix it.
Currently using V16.1
Thanks

Try telling us what you changed. This isn't a bug in Essentials, so it's something you've caused.

Hi, thanks for the reply.
I am fairly certain that I have not touched Echoed Voice anywhere.
I did try removing all the Echoed Voice stuff in the scripts just to see what happened, and I got the same message but for Trace, so I pasted the original file back into the script.
I had a quick look through PB Battler the only change which stood out was that I added a Sandstorm Castfrom form.
I couldn't see any other obvious changes to the script.
I could try and use MS word and use the compare function to find more differences between the original one and the one I have with the changes...
I will do that and get back here

You said you were using Essentials v16.1, but you're definitely not. What version are you using, and have you tried doing any upgrading?

I am using 16.1, but when I did upgrade, I did transfer a few scripts to which I had made changes to before 16.1, but I think I will need to start with the vanilla 16.1 and then add the small changes in one by one, because when I compared the scripts there are a tonne of differences which I am pretty sure I would not have made, cause I don't want to venture out and make changes to stuff I don't understand :P
So I will try that.

Thanks :)
