phpxmlsymfonyhosting

Symfony on webhosting is throwing Unable to parse XML file error. How can I resolve it?

I made web application using symfony framework. When I run this app on my computer, it runs without a problem. But when I upload it to webhosting, this error is thrown: Unable to parse file "/3w/users/f/foer.wz.cz/web/vendor/doctrine/doctrine-bundle/DependencyInjection/../Resources/config/dbal.xml": The XML file "/3w/users/f/foer.wz.cz/web/vendor/doctrine/doctrine-bundle/DependencyInjection/../Resources/config/dbal.xml" is not valid.

This error was thrown by different bundles as well, that I removed because they were only for development. But Doctrine bundle is not. I have no idea what could be the problem. I also tried to delete cache files, but not with php bin/console cache:clear because I dont have access to the console. Thanks for your help in advance.

Solution

  • I resolved my error by changing code on line 459

    from: $dom = XmlUtils::loadFile($file, $this->validateSchema(...));

    to: $dom = XmlUtils::loadFile($file, null);

    in file /vendor/symfony/dependency-injection/Loader/XmlFileLoader.php.

    I hope it doesn't ruin anything.
