Undefined variable: plugin_folder in ... /plugins/Customizer/Plugin.php on line 128

After upgrading my Kanboard instance from 1.2.9 to the current 1.2.18, the following message always appears in the log:

2021/03/01 15:15:36 [error] 16776 # 16776: * 675 FastCGI sent in stderr: "PHP message: PHP Notice: Undefined variable: plugin_folder in /var/www/html/kanboard/plugins/Customizer/Plugin.php on line 128PHP message: PHP Notice: Undefined variable: plugin_folder in /var/www/html/kanboard/plugins/Customizer/Plugin.php on line 129 "while reading response header from upstream, client: *. * . *. *, server: xx.xxxxx.xxx, request: "GET/?controller=SoundNotificationController&action=soundNotifications&plugin=SoundNotification&_=1614608036365 HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php7.4-fpm.sock:", host:" xx.xxxxx.xxx

This error also occurs when accessing the TaskViewController, UserAjaxController or the BoardViewController

I concur, I observed the same warning: the $plugin_folder is effectively not defined in the onStartup() method.

I fixed it by adding the $plugin_folder = basename(PLUGINS_DIR); directive as seen in the initialize() method:

     public function onStartup()
     {
+        $plugin_folder = basename(PLUGINS_DIR);
         Translator::load($this->languageModel->getCurrentLanguage(), __DIR__.'/Locale');
         $user_id = $this->customizerFileModel->getUserSessionId();
         $user_theme = $this->userMetadataModel->get($user_id, 'themeSelection', $this->configModel->get('themeSelection', $plugin_folder.'/Customizer/Assets/css/theme.css' ));

This missing $project_folder var was also throwing the following PHP Warning:

PHP Warning:  filemtime(): stat failed for /Customizer/Assets/css/theme.css in /.../kanboard/app/Helper/AssetHelper.php on line 37

I also had the following PHP Warning that I fixed by setting the ownership of the plugins/Customizer/Assets/css/userthemes to www-data (chown -R www-data: plugins/Customizer/Assets/css/userthemes):

PHP Warning:  unlink(plugins/Customizer/Assets/css/userthemes/.gitignore): Permission denied in /.../kanboard/plugins/Customizer/Plugin.php on line 30

when I get a chance I can add it to the repo, unless you want to make a PR.

Think this is all set now. Added plugin dir variable to onStartup(), and removed userthemes folder from inital folder structure, letting Customizer make the folder with 755 permissions and correct user, to avoid permissions issues in the future.
