I accidentally deleted the Markdown filter module from the file system while it was still enabled. So I installed it again, via the GUI.

Now I cannot load the module uninstall page - it says "The website encountered an unexpected error. Please try again later", and the message in the log says Drupal\Component\Plugin\Exception\PluginNotFoundException: The "markdown" plugin does not exist. in Drupal\Core\Plugin\DefaultPluginManager->doGetDefinition()

I have cleared caches, run cron, deleted sites/default/files/php ... all to no avail.

Any ideas?

Edit: I have just tried to enable the module again, and got this message: Unable to install Markdown filter, markdown.settings already exists in active configuration. I looked through the config and cache_config tables and cannot find this setting.

  • Try adding it manually in core.extension config, e.g. with drush or a single config export and import. Apparently the module was forcibly removed there without being uninstalled properly. – Berdir Apr 30 '17 at 18:48
  • Thanks Berdir. Any way to do that without shell access? I only have sftp. – naomi Apr 30 '17 at 22:55
  • Single config export and import can be done in the UI but the core.extension file might be excluded from that, as it's pretty special. You can do a full config export, download that as an archive in the UI, the extract it, change the file, upload it into the configured config sync folder (usually sites/default/files/config_SOMEHASH/sync) and then go to config sync to import it. – Berdir May 1 '17 at 8:14
  • I tried to do this using the import/export config GUI ( since it was not core.extension but markdown.settings that I needed to delete). However after exporting, extracting, deleting the file and then recompressing & importing, it said "Your file is uploaded and ready to import" but nothing showed on the sync tab. I fixed it in the DB, see my answer, – naomi May 2 '17 at 9:04

It turned out there was a markdown.settings entry in the database (in the config or cache_config table, I forget which). I deleted this row and then it was possible to install and then uninstall the module.
