I have just upgraded from EE2.1 to EE2.3.1 and it all seems to have gone ok. 1 small issue is that the image thumbnails are broken in the back-end for all my custom File fields. They are all using the built-in File module. It seems that there is an extra forward slash before the file path which is causing the issue.
Currently: //images/banners/_thumbs/banner-about.jpg
Should be: /images/banners/_thumbs/banner-about.jpg
However once the File manager is open (in the popup), the thumbnails display fine.
Anyone know how to fix this?
And also how do you get the File manager to display thumbnails by default instead of opening with a text list of images?
