Im using EE2.1.0 and Pixel and Tonics Matrix product, if I create the gallery demo, I get the above error…..
I have found this on the web:
as I understand EE uses this, am I correct in assuming that this is the cause of the error??
How do I go about fixing this? as surely if I edit the files myself then it may mess up any EE upgrades in the future?
Thanks
