I’m having the same dashboard issue. Planning to try a reupload of files, which I did manually with ftp to begin with.
I noticed in prior updates, and this one as well, that there are some files in the wp-includes folder that I cannot delete. I can’t change the permissions on them and get the error msg. that I don’t have permission to change or delete these. They’re the Crystal folder and some stuff in the js folder. I have just changed the names of these hoping to work around but, anyone else encounter this?
Meanwhile, will watch for admin an dashboard fixes…
