Anyone know how to fix this Wordpress error?

I attempted to log into the backend of my website today, and got and error message I wasn't expecting. I use Wordpress and I think that one of my plugins probably broke.

This is the error message I got.

Failed to load resource: the server responded with a status of 500 ()

Normally I would just change things from my wordpress dashboard but I can't access it and I have no experience directly editing the code on a website.

Any suggestions?

It's a problem of your server I guess.
Not a problem of WP.

Your website was hacked. restore backup and install firewall plugin

If it's one of your plugins try to rename the plugin folder through ftp this way all plugins get deactivated until you rename it again. After this try to activate every plugin one by one to find the one thats responsible for the error

Have a look at https://www.wpbeginner.com/wp-tutorials/how-to-fix-failed-to-load-resource-error-in-wordpress/#:~:text=The%20most%20common%20reason%20that,same%20URLs%20for%20both%20options. and https://www.wpbeginner.com/wp-tutorials/how-to-fix-the-internal-server-error-in-wordpress/
Both are from wpbeginner dot com, which is a legit and reputable website related to Wordpress related issues. It may be helpful to solve your issue or give you a better insight towards a solution. In the past a few articles from this website did help me resolve a few Wordpress related issues I had.

It seems to be hacked! Restore it from backup.

Check the error log lol. 500 error can have magnitude of reasons. It just means that something went wrong while trying to render the page you are viewing. Could be as stupid as a missing php extension.
