A language entry is missing: CUSTOM_PRODUCT_WORK

Good evening,
It isn't affecting my use of the site in any way that I have noticed but I get this message at the top of every page? 
A language entry is missing: CUSTOM_PRODUCT_WORK
My club banner seems to be staying on one image too but it used to flick between images!
Good luck finding any faults :-)

Hi,
Can you try clearing your browsers cache and restart it please.

I'm currently on my phone but I have cleared the cache and restarted my phone but it is still there! Just so you know, I am useless at technology but I have just managed to find my cache 

Ok cool, what phone is it ?
And what web browser are you using mate

I'm on a Samsung Galaxy S4, is my web browser Google Chrome? 

Ok thanks. I don't have an Android phone to test with.

Ginner  do you see this on yours ?

Try now mate please 

How did you manage that? Your like a god who can control the internet with the power of his mind    

I don't see that error message. 

To clear your cache go to settings from an open browser page and under privacy you should be able to clear all your history and take it from there 

Cheers Dave :-)

The man who did the actual code changes is a very helpful bloke and is happy to fix any issues we find after the search upgrade :-) 

All sorted now Ginner , 
Thank you for your help, lhasadreams
This site wouldn't be the best if it wasn't for you guys!
Keep up the good work and you will be kindly rewarded at AGM 2015 

I was getting this on my google chrome browser on my desktop so it wasn't limited to phones.
Seems ok now.

Cheers !!

Yes, it was a bug and Chrome specific - all fixed now
