Thanks for the quick reply Andrii. I unfortunately only have the site running locally at this stage, I can put it on another url if you need to log in to look into the error.
I’m currently running 1.6 and the error has persists but I have now noticed that this error only occurs when the portfolio is set to the home page, when the portfolio is not set as the home page, the next – previous page buttons work fine. Hopefully that info helps.
Thanks,
Oli
