Try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.
If that does not resolve the issue, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel (consult your hosting provider’s documentation for specifics on these), navigate to /wp-content/themes/ and rename the directory of your currently active theme. Hopefully, this will force the default theme to activate and rule out a theme-specific issue (theme functions can interfere like plugins).
manually resetting didn’t help (though it’s a little different now)
- the theme folder has many folders with themes, how do I find my theme? (sorry for stupid questions)
You have activated PHP 8.2 or newer. The plugin you are using, “Download Plugins and Themes in ZIP from Dashboard”, is not compatible with this PHP-version. There is also a topic about this in their support forum: https://projectdmc.org/support/topic/php-8-2-error-message/ – have you installed an outdated version of the plugin? That would explain the message.
If it is the current version, I would recommend that you remove the directory /mnt/web301/a2/38/59957038/htdocs/wordpress/wp-content/plugins/download-plugins-dashboard/ via FTP. Your web should then work again. However, you will no longer have the functions of this plugin.
Alternatively, you could try changing the PHP version to an older one, e.g. PHP 8.0 or even 7.4. To do this, you would need to contact your hoster’s support team.
However, I am totally surprised by the 2 paths in your error message:
/mnt/web301/a2/38/59957038/htdocs/wordpress/wp-content/plugins/includes/settings/class-alg-download-plugins-settings.php
/mnt/web301/a2/38/59957038/htdocs/wordpress/wp-content/plugins/download-plugins-from-dashboard.phpThis does not exist and cannot exist according to the current scheme for plugins. A plugin called “includes” would be very strange. Please also check the plugin directory via FTP to see what it looks like. It should consist of subfolders – one for each plugin. However, if it looks as chaotic as the log makes it appear, you either have an ancient WordPress installation or your project is set up incorrectly overall.
I tried renaming the download-plugins-dashboard.php file and now I get this error:

sorry: includes has the file class-alg-download-plugins-core.php and two folders: settings and js
I changed to php 8.1 but I can’t go lower it seems (strato)
I meant a directory, not a file. Does the directory not exist but only a file called download-plugins-dashboard.php ? Then the plugin has obviously been stored completely incorrectly in the plugin directory.
Can you connect via FTP and show a screenshot of the directory /mnt/web301/a2/38/59957038/htdocs/wordpress/wp-content/plugins/? How you can provide it here is described here: https://projectdmc.org/support/forum-user-guide/block-editor/#adding-screenshots
I also don’t understand how you can get such an error message when renaming a file. How did you try to rename the file? I would recommend using FTP. But renaming won’t help much.
