Any time I select an admin option i get the below error.
Error: Class 'Drupal\Core\Form\FormErrorHandler' not found in Drupal\Component\DependencyInjection\Container->createService() (line 258 of core\lib\Drupal\Component\DependencyInjection\Container.php).
I have cleared my cache and restarted wamp, not sure what the next step is.
If I get an error that is in a core or contributed module and clearing cache and and server restart doesn't help, I usually try running database updates next to see if any where missed.
Have you run the update.php? if that fails you could try using drush to run the update.php using drush updb
If that doesn't work I would run a backup of the codebase and db then try updating the modules, then update core using drush drush up
Restarted my PC and that seemed to work. I have no idea what the error is linked to, but that seems to work if anyone is having the same issue.

I installed latest open social 11.7.0 distribution for Drupal 9 using composer. Smoothly and setup went fine.
However when updating using composer update it takes ages to finally cast a killed message. Output is not really verbose and I don't have a clue what happens behind the scene. I saw it could be "memory usage" related but bypassing memory limit usage ends in same result.
To be mentioned I have an other classic drupal website on same server and composer update runs like a charm.
Any advice or idea ?
Thx beforehand,
I am upgrading my drupal project from 8.9 to 9.3.5 but after the upgrade while hitting website one error occur i.e
The website encountered an unexpected error. Please try again later.
I followed the steps mentioned in the drupal site for upgrading drupal from 8 to 9 or (later) click here for steps but didn't work for me.
Will anyone please help me or provide proper steps to upgrade drupal from 8.9 to 9.3.5?
You should try to get more information about the error.
Add to your settings.php file:
$config['system.logging']['error_level'] = 'verbose';
and check the output on your screen again.
You may also try drush to take a look at selecting the option errors from the terminal.
drush watchdog:list
I've run into this same issue multiple times. If you haven't already done so, try going to /update.php multiple times. (It seems to clear out the update process junk/leftovers and let it work.)
Other than that, it's always some kind of file issue. (I still update manually due to my server setup.) Sometimes it was a folder/sub folder that didn't upload fully or other times it was that some module simply refused to work with the new upgrade until that was updated.
my Symfony 3 app works flawless on my local webserver. Since it´s been installed on the remote web server it produces a blank page, even the routing doesn't work. After editing web/app.php $kernel = new AppKernel('prod', false); and set it to true, the application works as expected and does not display any errors.
Why does the application behave different on the local and the remote webserver. Did I miss to configure something on the remote server?
Any suggestions?
Thanks in advance!
Finally I have a solution to solve the problem: after the composer update I have to clear the cache of the prod environment manually by executing rm -fr var/cache/prod/*. For whatever reason does the command php bin/console cache:clear --env=prod quit working immediately after the composer update without throwing any error messages. After removing the cache files manually both the application and the cache:clear command work as expected without modifying web/app.php.
1.check permission to cache and log dirs ( need to be 777 )
2.check (paste here) error in logs/prod.log
Since I couldn´t find out what´s the real cause of this problem I´ve made a fresh install of my application and updated Symfony and all dependencies with composer.
Although I did the same with the old installation, it does the trick this time. My guess is, something went wrong with the composer update before.
Thanks again for your help! If someone has a similar problem I would appreciate if you could post how you solved the problem (or why AppKernel['prod'] = 'true' did work).
I have plausible explanation, what might have been the problem.
I have encountered this problem earlier this year with Symfony3, while developing on Windows but deploying manually (copying project's files) to shared server with Linux.
As you say - blank page in prod environment.
To add to the mystery log files did not show any problems
So i enabled dev environment to check what is wrong
application worked as intended if i added app_dev.php in the URL
I overviewed all the files, more than once, but copy was done correctly.
The answer
After some time I "came across" the file: bootstrap.php.cache in var directory. It "felt suspicious".
As I had exhausted my options i just deleted it to test the result.
That solved it in my case.
Site was running again.
No more blank page!
I guess mixed development environment has its toll.
I have been using meteor framework for the past few days. Now, when i create a new project it downloads meteor-tool#1.3.2_4. But it does not complete download. It seems to be stuck at downloading and shows only following line:
Downloading meteor-tool#1.3.2_4...
How can i troubleshoot this issue.
I got it to download by adding 54.192.225.217 warehouse.meteor.com to /etc/hosts
There's a GitHub issue about it here.
As I haven't found this answer elsewhere with this search and can save some time:
In windows 7, this happened to me because I forgot to run meteor -create in a console with administrator rights.
Just Run As Administrator and check again.
Hope it helps
This is caused by a permissions issue. As workaround, try running the create command with super user permissions:
sudo meteor create myAppName
Probably you will need special permissions for running the app too:
/MyAppName> sudo meteor
If you want to stop running meteor commands with super user permissions, check this: Meteor will not run without Sudo?
I've seen it myself on Mac OS while i run 'meteor update'.
Then i run "ping warehouse.meteor.com" on shell.
And I found that meteor's network service is not good, just try it at other times.
I've been trying to install Meteorjs on windows but error occurs. I already tried downloading another installer and restarting my computer but it doesn't work. It always pops 'failed to contact install server. Please try again' then displays the message 'One or more issues caused the setup to fail. Please fix the issues and then retry setup. For more information see the log file.'
Under that it displays '0x80070643. Fatal Error during installation.'
what to do with this?
One option is to run meteor preview for windows. Believe it is a standalone copy of meteor 1.1
https://github.com/meteor/meteor/wiki/Preview-of-Meteor-on-Windows
(this doesn't address the issue of connecting to server though because when you try to create a meteor account you get a similar error).
there definitely is a way to install through command line on windows (which annoyingly I can't remember from my other machine). Perhaps through npm...
Try to run the package as administrator.It works!
Try this guide.
Download .zip, then unzip and set path environment variable.
