fof links, class not found

pentarou please post the output of php flarum info thank you.

pentarou Was the extension enabled when you ran php flarum info ? The only enabled extensions are the core ones...

pentarou

@datitisev I try to only use core extensions, I've removed the FoF Links extension, as I was unable to access the configuration panel, here's the output with the extension installed and enabled:

clarkwinkelmann

You could try running composer dump-autoload in the Flarum root folder to re-create the loader files.

pentarou

@clarkwinkelmann I tried your solution and cleared the cache, but it didn't solve the problem, here is the output:

Generating autoload filesCarbon 1 is deprecated, see how to migrate to Carbon 2. https://carbon.nesbot.com/docs/#api-carbon-2 You can run './vendor/bin/upgrade-carbon' to get help in updating carbon and other frameworks and libraries that depend on it. Generated autoload files containing 11 classes

datitisev

pentarou That is not an error, that's a warning that can safely be ignored.

clarkwinkelmann

pentarou the Carbon warning can be ignored. The Composer command seems to have been successful.

So still the same error when trying to access the forum ?

Here are a few others things that might help us troubleshoot:

Can you tell us what kind of server this is (managed, VPS ?) and how it was configured ?
Can you post the output of cat vendor/composer/autoload_psr4.php | grep FoF ? This will tell us if Composer has registered the autoloader for the extension or not.
Also can you check if vendor/fof/links/src/Listener/AddLinksRelationship.php exists ?
Could you try enabling display_errors in your PHP config as described in https://flarum.org/docs/troubleshoot.html#step-1-turn-on-debug-mode and try again ?

If it's registered and it exists I don't know what could cause the files to not be found. Could it be something related to php 7.3 ? 🤔

datitisev

clarkwinkelmann Could it be something related to php 7.3 ?

Oh, I didn't even notice it was PHP 7.3. Other people have been having issues on PHP 7.3, so that is most likely the cause. I think it's a composer issue, but not entirely sure.

clarkwinkelmann Unfortunately the same error still occurs:

VPS Plesk Onyx Version 17.8.11 Update #56 | 1024M memory_limit | Subdomain
Output 'FoF\\Links\\' => array($vendorDir . '/fof/links/src'), (FoF displayed in red text color)
Path and file vendor/fof/links/src/Listener/AddLinksRelationship.php does exist
Enabled display_errors in php.ini but nothing new shows in both front-end and PHP error log
PHP Version: 7.2.19 gives the same error @datitisev, clarkwinkelmann

datitisev

pentarou Try deleting the vendor folder and running composer install on PHP 7.2.

pentarou

datitisev I have deleted the vendor directory in SSH using rm -rf vendor, confirmed using PHP 7.2 in both domain and shell and executed the composer install command. The vendor directory reappears. I have cleared the Flarum and browser cache, and restart the server, but it still outputs the same error in the front-end.

clarkwinkelmann

pentarou can you tell us what operating system / hosting you're using ?

pentarou

clarkwinkelmann Sure, I use BladeVPS by TransIP, running Plesk Onyx Version 17.8.11 on centos-release-7-6.1810.2.el7.centos.x86_64

pentarou

The same error applies to other extensions like Discussion views as well, but with another class of course, so I don't think the extensions are the problem.

pentarou

There were some duplicate folders such as vendor outside the Flarum root (httpdocs) folder, so I deleted it and it started throwing errors such as Warning: require (../ vendor / autoload.php): could not open the stream: no file or directory which made me think that flarum may have used files and directories outside the httpdocs directory, perhaps this is related to the errors regarding the extensions.

Any thoughts on this?

luceos

pentarou that might be the cause yeah, without an idea of the actual structure and paths configuration it's hard to say. But the error proves that you've been trying to fix the wrong vendor folder.

pentarou

luceos

I recall having to move Flarum from a folder to the root because that's how it was initially installed, there must have been a mistake from my side. I changed line 12 in index.php to vendor/autoload.php and now works normally, even with the extension installed and enabled.

Thanks for the help, is there something more I need to look at?

luceos

pentarou I changed line 12 in index.php to vendor/autoload.php

Do not touch any file inside vendor, that's not how to solve this issue. Please provide the line you changed and the directory structure you have now.

edit: you should be able to delete vendor at all times and get to the same state by running composer install.
