On the Plugins screen I have options to activate and deactivate plugins, but I no longer have the "Delete" option. I'm relatively sure the option appeared earlier.
Also, when I hover over "Plugins" on the admin menu I don't get the usual popup submenu showing "Install New / Add / Editor". And when I click the Plugins menu I don't see those submenu options either.
What's gone wrong?
FWIW, the client I'm working for is hosted at GoDaddy.
D'oh.
I fixed it, but I'll leave this question in case others have similar problems.
When copy/pasting various options into wp-config.php I accidentally included this setting, which I don't normally use:
// Overkill but FYI: disallows installation/updating of any theme or plugin
define('DISALLOW_FILE_MODS',true);
That produces the described problem, albeit by design.
This help me a lot, actually I had 2 options active on my wp-config (never added them)
define('DISALLOW_FILE_EDIT', true);
define('DISALLOW_FILE_MODS', true);
just set the mode to false and problem solve itself...
5 years after but I guess I´ll add my 2 cents. Don´t choose the plugin option on the left bar menu. instead, go to the top left on your screen and hover on my sites and on that sub-menu then hover on network admin and choose plugins there. Once that is done you will get the missing sub menu option to add new and the delete option will also become available once again on the activate, deactivate sub menu as well. cheers
This helped me. Somehow it was there and i have never put it myself.
Change define('DISALLOW_FILE_MODS',true); to
define('DISALLOW_FILE_MODS',false );
