Hi guys,
Just downloaded the plugin to install and migrate a phpBB forum I have on another site. I was greeted with this on activation:
“The plugin does not have a valid header.”
I downloaded the ZIP on a Mac, installed without opening or modifying it. I used WinZip to verify the content of the file and it seems fine (I can open, browse and look at the content–it looks “plugin like”)
But I still get that error. Any thoughts on how to get around it??
