You need to upgrade your PHP version to a minimum of 5.4, preferably 5.5 if available. Try that and see if it helps, get back to us once you’ve done this.
If you need to install plugins manually, then Follow the instructions given on the CKEditor plugin page.
@erik6 Have you changed the value of the plugins directory in your config file?
But CKEditor is now included in the phplist release so you shouldn’t need to install it.
Please explain more precisely what you have done.
The current phplist release is 3.2.4 so you should install that instead of 3.2.3.
Also, as suggested, you need to upgrade your version of php as that may also be causing problems.
My hosting company updated my PHp and PHplist software.
Still, the menu is not available in the editor in Phplist.
I have installed the program in the ROOT directory of the site.
If the Manage Plugins page has no plugins listed then it appears that you have not installed phplist correctly. That page should show the CKEditor plugin and the fckeditor plugin, which are both included in phplist.
Are you saying that you have installed in the phplist directory instead of the lists directory? So you access phplist as mysite.com/phplist/admin ?
So long as you have copied all of the files then the two plugins should be available.
Have you changed the value for the plugin directory in your config file?
