PluginNotFoundException: "The "" plugin does not exist." on new server

By Didier Misson on 1 May 2016 at 04:48 UTC

Hello

I have a D8.1.0 site running on a "old" server : Ubuntu 14.04 LTS with PHP 5.5

I want to move to a new sever : Ubuntu 16.04 LTS with PHP 7.0

I make a drush backup
and a drush restore on a new server.

I make drush cr before trying to access to the site.

But I receive error message :

The website encountered an unexpected error. Please try again later.

In the Apache2 log :

[Sun May 01 15:37:48.449412 2016] [:error] [pid 1281] [client 87.66.35.0:59742] Uncaught PHP Exception Drupal\\Component\\Plugin\\Exception\\PluginNotFoundException: "The "" plugin does not exist." at /home/mysite/public_html/core/lib/Drupal/Component/Plugin/Discovery/DiscoveryTrait.php line 52

No idea... as I only "drush backup / restore" ...

Thanks
;-)

Resolved In My case GD Library andImage toolit was not installed, on the server so please if any one finds this type of issue please check your logs or status report in reports section. It can be a server configuration issue.

Same here, my problem was

Same here, my problem was also that the correct gd library was not installed since I just updated to php7.1 on my server. Installed the needed extension by executing `sudo apt-get install php7.1-gd`

Thank You for the suggestion

I too had the same problen. Was solved by installing the php gd library. Thank you for the suggestion.

Thanks

Yes, in my case GD library was not installed. After installing it , it is working fine.

Same issue

rich_dawson commented 6 August 2016 at 14:21

I am experiencing the same issue when visiting the user settings page only. No idea when this started exactly, or what modules may be involved as the error is very unhelpful. Server logs on NGINX are non-existent for this particular error on my local machine. No errors reported on host servers either.

Module Missing Error

harsh.behl commented 6 August 2016 at 16:02

This issue is particularly come inthe absence of any module either php or drupal, in my case it came due to the missing of image tool kit, gd library which was being used to upload images. In your case on user settings page there will be any module or php extension that may be missing, you need to dig into this yourself, One important thing you can recheck with admin/reports/status report section in admin panel. If any php extension is missing taht will be highlighted there otherwise it is purely module missing error.

Hope this helps.......

My case

This was my case after switching to ppa:ondrej/php
So, sudo apt-get install php5.6-gd fixed the issue in my case.

Thanks

Same problem, similar solution

Strompf commented 1 March 2017 at 17:13

Hi folks,

Thank you for the solution, Hugronaphor! I had a similar problem: In Drupal Commerce 8, I couldn't upload images without running into this error.

This webserver is only a couple of months old. I started with PHP 7.1, but when that was too challenging for my patience, I switched back to PHP 7.0, but I forget to install the relevant libraries, including GD: I had the PHP 7.1 library, but only the needed PHP 7.0 library, after sudo apt-get install php7.0-gd

Thank you very much!

Thank you very much!

This was the solution for me too.

thanks guys!

I was dealing with this issue for a long time, problem solved with "sudo apt-get install php5.6-gd"
Many thanks,

Try doing a new Drupal site installation

Vivek Panicker commented 3 November 2017 at 07:13

Try installing a new Drupal site. If some php module is missing, which is most probably the case, then it will be visible in the list of requirements.

I had just update to php7.0 and the gd library was missing. So I read the comments above and installed it and the site was working fine.

Then I got the idea of doing a new drupal installation to check if any php module required by Drupal is missing.

Had the same problem with

baltazarz3 commented 5 December 2017 at 18:09

Had the same problem with drush version: 8.1.15 on a Drupal 8.4.2 site, php 7.1. This got fixed by installing GD library

For PHP 7.2 sudo apt-get

fazni commented 15 May 2018 at 15:18

For PHP 7.2 sudo apt-get install php7.2-gd

For PHP 7.1 sudo apt-get install php7.1-gd

Solved - Issue related to server configuration

nexgeninnovators commented 12 December 2019 at 07:51

This error comes when Drupal isn't getting some required configuration active to work. Like GD library updated version - which is being used by imageToolkit.

One solution - You have to resolve all issues in admin status - admin/reports/status

and things will be set!

Common error:

1. gd library not installed or outdated:

First, check your package using php -m

In list gd should be there - but sometimes it's outdate. to update check your php version. e.g I'm using php 7.0 then

To install PHP GD extension on an Amazon Linux AMI server, with php 7:
sudo yum install php 70-gd

For all who use php 7 and ubuntu
sudo apt-get install php7.0-gd

Do remember to restart Apache after the installation!
sudo service httpd restart

for more you can follow official documentation - https://www.php.net/manual/en/image.installation.php

After doing this -

go back to the issue list in the admin panel and refresh the page. If the issue removed - you are done!

2. files are not writeable

go in root folder of your project and run following command:

chmod -R sites/default/files (It will make files and it's child folders writable)

No need server restart.

go back to the issue list in the admin panel and refresh the page. If the issue removed - you are done!
