Support » Plugins » Not able to add or see new plugins

  • Hello, have a vexing problem. I am trying to load new plugins and after uploading them I cannot see them in the list where I would normally find them (inactive plugins). Also, when I try to upload using the “Install a plugin in .zip format” feature, I get the error message that says “Unable to create directory /public_html/ Is its parent directory writable by the server?”

    I can still see and manage the existing plugins that were installed a while ago. The site I am trying to add to is one that I haven’t tended to for a few months, so not sure when this glitch started. However, I did have my sites moved from a shared to a VPS just a few days ago. It’s my thought that something about the move may have corrupted something.

    But, I also have another WP install on the same host, but in a different DB. I have no problems adding plugins to that one.

    I have no problems reinstalling WP, but if anybody has some ideas to try first, please be my guest.

  • I am assuming that is a folder in your web area. If not, you have a misconfigured blog location.

    First go to admin / settings / misc and make sure the file upload path points to a location on your site that actually exists. If not, change it and try the plugins again.

    Otherwise, this means WP does not have permission to write a new folder in your file uploads area. There are many posts on this forum about permissions problems. My suggestion would be to contact your webhost and ask them how they recommend setting up permissions on the uploads folder to accomplish what you want to do.

    I have posted a similar problem. I get the error message:

    Fatal error: Cannot redeclare uninstall_plugin() (previously declared in /home/MY NAME/public_html/MY SITE/wp-admin/includes/plugin.php:509) in /home/MY NAME/public_html/MY SITE/wp-content/plugins/pluginstaller/uninstall.php on line 89

    It started after I upgraded to WP 2.7.

    Any suggestions?

    You have a plugin installed called pluginstaller that is causing your problem

    Using FTP or the Cpanel file manager, get into the file structure on your webhosting account. Within folder /wp-content/plugins/ is a folder called pluginstaller move that entire folder into the folder /wp-content/ and out of the folder /wp-content/plugins/

    Then try again. That should resolve your problem. If it works you can delete the folder pluginstaller as that plugin is not working correctly with 2.7 You probably don’t need it anyway as 2.7 contains the option to install plugins from WP within the core WP code.
