@Jan - thanks for your reply. Yes, I was able to edit them before. I also actually had the same issue with the dashboard, before even adding the Members plugin, and still have that issue, so not sure if that's it. So basically, I can't edit the dashboard or the widgets in appearance > widgets. And I've de-installed (using recommended method) Adminimize and re-installed it as I seem to have an issue each time. Just seems really buggy but I'm determined to make it work because this plugin does (almost :) ) everything I need.
@Frank thanks - It's the widgets under Appearance > widgets (the widgets that populate my sidebars). I'm not sure if this is what you meant but I opened "screen option" at the top and selected "enable accessibility mode" (didn't notice this before)- I can now edit the widgets but cannot move them around or drag and drop them, and each time I edit them they open in a new window. I still can't edit my dashboard though (before I used to be able to move the boxes around). Is this normal?
I also recently upgraded my wordpress hoping it would help. I didn't test this in the previous version, so not sure if this is it.
I double-checked to see if it was site wide, but I can still move my menu items under appearance > menus (rearrange the order and edit the links etc).
