WordPress – Unable to Update Plugin


Today I had an interesting problem while adding and updating the Akismet plugin on a client’s site.  It just would not work.  I could add and update other plugins, just not Akismet.  I got error message dealing the the file.php in the wp-admin/includes directory.


I did some research.  While this issue was showing up for me on the Akismet plugin, I don’t think it caused the issue.  I’m actually not sure what caused the problem, but I did find a fix.

Step One – Add the following line of code to the config file:

define( 'WP_TEMP_DIR', ABSPATH . 'wp-content/tmp/') ;

Step Two – Make a file folder called “tmp” in the wp-content directory.  Set the permissions to 755.

Step Three – Add or update the plugin of your choice.
