Today I logged in two mine community where Byoblu (to version 1.3.2) and Merge Discussions (to 1.4.1) was require an update.
In one community I checked updated with Package Manager v1.0.0-beta.2 and update one by one extension, in total 2.
In the other community I run the global update.
Same situation two extensions to update but in this case the page get blank and community was down.
An error 500 was visible from the developer console.
I logged into the server and found the following error:
AH01071: Got error 'PHP message: PHP Warning: require(/flarum/vendor/composer/../symfony/string/Resources/functions.php): Failed to open stream: No such file or directory in /flarum/vendor/composer/autoload_real.php on line 41PHP message: PHP Fatal error: Uncaught Error: Failed opening required '/flarum/vendor/composer/../symfony/string/Resources/functions.php' (include_path='.:/opt/plesk/php/8.1/share/pear') in /flarum/vendor/composer/autoload_real.php:41\nStack trace:\n#0 /flarum/vendor/composer/autoload_real.php(45): {closure}()\n#1 /flarum/vendor/autoload.php(25): ComposerAutoloaderInit95249f298fe30bae0797ff96b70cba84::getLoader()\n#2 /flarum/public/index.php(12): require('...')\n#3 {main}\n thrown in /flarum/vendor/composer/autoload_real.php on line 41'
I saved myself by finding an old post in the community and a reply from luceos to run composer install
I suppose the blank page it's an issue that should be not happen when run Package Manager so I'm reporting here.
Also the issue happen only in one community... the community where i run the global update. In the other community upgrading one by one plugin never created issues.
