I am having the same problem with being unable to install new plugins.
I have been using WordPress for over a year on various domains and
hosting companies, the last successful installation was about 2 weeks
ago.
Now when I install WordPress I do not have the option to install new
under plugins. I thought I had done something wrong so I uninstalled
Wordpress from my domain and then went in to reinstall it. It
installed so far and then said I needed to delete manually the
files wp-admin, wp-content and wp-includes and then try again to install.
I went into File Manager and deleted the 3 files, but everytime I
checked to make sure they were deleted they had come back again.
I tried deleting through File Manager several times and then tried
deleting through Filezilla. Everytime they came back again and I
cannot reinstall WordPress until they are deleted.
Any ideas how I can do this. I have been trying this now for 3 days and am climbing the wall with it. I have tried different domains and different hosting company but they are all the same. I thought it was maybe the latest update of WordPress which is 3.3.1 but my successful
installation 2 weeks ago was on 3.3.1.
Can anybody help me PLEASE
Thanks
