define('PLUGIN_INSTALLER', true);



I have the plugin setting set to true in my config.php which is located in my data dir …

The permissions on the plugin are set to 755.

Is there something else that needs setting, i still get the message to say plugins disabled from the user interface ?


config.php should be in your app folder.

And when i say app folder, not to be confused with the app folder inside the app folder.

As in



I have it in:



Is there an app folder in your app folder? If not, then its in the wrong folder and should be in your kanboard folder. If so…we’ll deal with that later…


Nope there’s no app folder in the app folder, I’ve tried with the config.php in the app folder and in the root of the kanboard dir with the same result sadly.


What are the contents of your config.php


Defaulft other then plugin enablement i think:


Rename this file to config.php if you want to change the values /

Really not sure, try changing something else in your config, and see if it holds true, like set up smtp.


There are three requirements to enable plugin directory feature:

  • The plugin directory must be writeable by the web server user
  • The Zip extension must be available on your server
  • The config parameter PLUGIN_INSTALLER must be set to true

Apparently you have the first and third conditions, please check if you have the zip extension enabled

Place config.php inside public_html/kanboard/ folder. Note that your PLUGINS_DIR is set to DIR.DIRECTORY_SEPARATOR.'plugins', so there should be a plugin folder inside the same folder config.php is (because of DIR). This is the default, public_html/kanboard/plugins. This folder should be writeable by webserver user. By setting 755 you have to check if the webserver user is the owner of plugins folder.


Nailed it …

“The Zip extension must be available on your server”

It was on for all versions bar the version of PHP in use.

All sorted, many thanks @rafaelcamargo and @creecros for your support on this.
