Hello, I've looked searched through the forums and found similar problems but have not found a solution to this.
I noticed today that if I try to fo to "Updates" in the Dashboard, I am taken to "mydomain.com/wp-admin/update-core.php", but a 404 page.
I keep getting a 404 page when I try to view the plugins page (sometimes), and always when after uploading a plugin, or clicking on "featured, "Popular", "Newest", and "Favorites" in the Plugins page.
Same happens when clicking on "Featured", "Newest", and "Recently Updated".
Relevant info might be that I have a second WP install in a subdirectory, for a site I'm developing,which shows the same issues. However, up until yesterday, it was working just fine and I was able to install plugins and themes no problem.
Any clues / suggestions will be much appreciated. Thank you!
