I'm having a big problem.
My SD Field Concat stopped working, I think it was after upgrading Joomla, when I walk into the fields already created, you see a white screen when I try to create a new field using it, nothing appears.
I believe it can be resolved by upgrading, but tried to find the place to download the update and did not. I bought it in 2012.
How can I solve this?
Thank you
