I saw a few persons having similar problems as this after upgrading to 2.0.3.
Myself: not able to delete link(s)
Others: not able to delete post, categaries etc.
I didnt receive any error msg. The browser refreshed after i clicked on the delete button. But the link remained there. (and yes, i did clear my cache and refresh the browser, tried a few times too)
Can somebody pls help?
