I installed NC 25.0.2 using the web installer. The instalation was not smooth. When redirecting to the “apps” page, the url was wrong. After a few attempts I got to the right url and NC behaved like everything was fine. However, it is not actually working. I can log in and navegate on the web interface, but none of the apps is actually working: I cant uplod files, create tasks, etc. For every action I try I get “This operation is not allowed” (not sure if this is the english message since the interface is in Portuguese and I cant change it). The basic system info is: ```auto **Operating system:** Linux 3.10.0-693.2.2.el7.x86_64 #1 SMP Tue Sep 12 22:26:13 UTC 2017 x86_64 **Webserver:** Apache (fpm-fcgi) **Database:** sqlite3 3.7.17 **PHP version:** 8.1.12 Modules loaded: Core, date, libxml, pcre, sqlite3, ctype, dom, fileinfo, filter, ftp, hash, iconv, json, SPL, session, PDO, pdo_sqlite, openssl, posix, Reflection, standard, SimpleXML, tokenizer, xml, xmlreader, xmlwriter, mysqlnd, cgi-fcgi, bcmath, curl, calendar, gd, gmp, intl, imap, mbstring, exif, mysqli, zlib, pcntl, pspell, pdo_mysql, pdo_pgsql, pgsql, zip, Phar, amqp, imagick, mcrypt, mongodb, OAuth, sqlsrv, pdo_sqlsrv, psr, redis, timezonedb, soap, xsl, newrelic, ionCube Loader, Zend OPcache **Nextcloud version:** 25.0.2 - 25.0.2.3 ``` When trying to find out the reason, I got to the config file and its content seems weird, shorter than it should be. ```auto 'xxx', 'passwordsalt' => 'xxx', 'secret' => 'xxx', 'trusted_domains' => array ( 0 => 'xxx', ), 'datadirectory' => 'xxx', 'dbtype' => 'sqlite3', 'version' => '25.0.2.3', 'overwrite.cli.url' => 'xxx', 'installed' => true, ); ``` So, no info about database and so on. Any ideas on what happened and on how to fix this? ---

Also, under Administration → Overview, I am getting two error messages. Unfortubately, they are in portuguese and I cant change the language. The first is about “webdav is broken”. The second is about PHP memory been below 512 MB. ---

you are still missing **lot** of important information - especially logs. > [@barichello](#): > > `Linux 3.10.0-693.2.2.el7.x86_64 #1 SMP Tue Sep 12 22:26:13 UTC 2017 x86_64` 5y old kernel sounds really _strange_ **and** _old_… are you running some weird NAS/IoT device? even my outdated Qnap-453 runs 5.10 kernel from 2022… ---

It is running on a basic hosting service I use for a long time now ([umbler.com](http://umbler.com)). The latest error message in the log file (and the only one that seems relevant) is this: ```auto {"reqId":"Y7R9ruM2INkLyT6ny0uCNQAHktc","level":3,"time":"2023-01-03T19:10:38+00:00","remoteAddr":"187.106.251.242","user":"admin","app":"index","method":"GET","url":"/nextcloud/index.php/settings/admin/serverinfo","message":"Call to undefined function OCA\\ServerInfo\\OperatingSystems\\shell_exec() in file '/home/mais.mat.br/public/nextcloud/apps/serverinfo/lib/OperatingSystems/DefaultOs.php' line 248","userAgent":"Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:108.0) Gecko/20100101 Firefox/108.0","version":"25.0.2.3","exception":{"Exception":"Exception","Message":"Call to undefined function OCA\\ServerInfo\\OperatingSystems\\shell_exec() in file '/home/mais.mat.br/public/nextcloud/apps/serverinfo/lib/OperatingSystems/DefaultOs.php' line 248","Code":0,"Trace":[{"file":"/home/mais.mat.br/public/nextcloud/lib/private/AppFramework/App.php","line":172,"function":"dispatch","class":"OC\\AppFramework\\Http\\Dispatcher","type":"->"},{"file":"/home/mais.mat.br/public/nextcloud/lib/private/Route/Router.php","line":298,"function":"main","class":"OC\\AppFramework\\App","type":"::"},{"file":"/home/mais.mat.br/public/nextcloud/lib/base.php","line":1047,"function":"match","class":"OC\\Route\\Router","type":"->"},{"file":"/home/mais.mat.br/public/nextcloud/index.php","line":36,"function":"handleRequest","class":"OC","type":"::"}],"File":"/home/mais.mat.br/public/nextcloud/lib/private/AppFramework/Http/Dispatcher.php","Line":165,"Previous":{"Exception":"Error","Message":"Call to undefined function OCA\\ServerInfo\\OperatingSystems\\shell_exec()","Code":0,"Trace":[{"file":"/home/mais.mat.br/public/nextcloud/apps/serverinfo/lib/OperatingSystems/DefaultOs.php","line":186,"function":"executeCommand","class":"OCA\\ServerInfo\\OperatingSystems\\DefaultOs","type":"->"},{"file":"/home/mais.mat.br/public/nextcloud/apps/serverinfo/lib/Os.php","line":78,"function":"getDiskInfo","class":"OCA\\ServerInfo\\OperatingSystems\\DefaultOs","type":"->"},{"file":"/home/mais.mat.br/public/nextcloud/apps/serverinfo/lib/Settings/AdminSettings.php","line":79,"function":"getDiskInfo","class":"OCA\\ServerInfo\\Os","type":"->"},{"file":"/home/mais.mat.br/public/nextcloud/apps/settings/lib/Controller/CommonSettingsTrait.php","line":129,"function":"getForm","class":"OCA\\ServerInfo\\Settings\\AdminSettings","type":"->"},{"file":"/home/mais.mat.br/public/nextcloud/apps/settings/lib/Controller/AdminSettingsController.php","line":83,"function":"formatSettings","class":"OCA\\Settings\\Controller\\AdminSettingsController","type":"->"},{"file":"/home/mais.mat.br/public/nextcloud/apps/settings/lib/Controller/CommonSettingsTrait.php","line":149,"function":"getSettings","class":"OCA\\Settings\\Controller\\AdminSettingsController","type":"->"},{"file":"/home/mais.mat.br/public/nextcloud/apps/settings/lib/Controller/AdminSettingsController.php","line":68,"function":"getIndexResponse","class":"OCA\\Settings\\Controller\\AdminSettingsController","type":"->"},{"file":"/home/mais.mat.br/public/nextcloud/lib/private/AppFramework/Http/Dispatcher.php","line":225,"function":"index","class":"OCA\\Settings\\Controller\\AdminSettingsController","type":"->"},{"file":"/home/mais.mat.br/public/nextcloud/lib/private/AppFramework/Http/Dispatcher.php","line":133,"function":"executeController","class":"OC\\AppFramework\\Http\\Dispatcher","type":"->"},{"file":"/home/mais.mat.br/public/nextcloud/lib/private/AppFramework/App.php","line":172,"function":"dispatch","class":"OC\\AppFramework\\Http\\Dispatcher","type":"->"},{"file":"/home/mais.mat.br/public/nextcloud/lib/private/Route/Router.php","line":298,"function":"main","class":"OC\\AppFramework\\App","type":"::"},{"file":"/home/mais.mat.br/public/nextcloud/lib/base.php","line":1047,"function":"match","class":"OC\\Route\\Router","type":"->"},{"file":"/home/mais.mat.br/public/nextcloud/index.php","line":36,"function":"handleRequest","class":"OC","type":"::"}],"File":"/home/mais.mat.br/public/nextcloud/apps/serverinfo/lib/OperatingSystems/DefaultOs.php","Line":248},"CustomMessage":"--"},"id":"63b49b18be4ac"} ``` ---

I am not sure it is the only problem, but shell\_exec is disabled on my host. Thanks for the help! ---
