Can't use Flarum in NGINX subdirectory

feds

The issue

Hello everyone, I was able to install Flarum on my WordPress subdirectory (/forum). But, when I try to use it, I face some problems: The requested resource was not found., where in "Debug" says that it's trying to get /public/api/tags

I'm currently working on mydomain.com/forum/public (I'm planning to remove this later), and Flarum gives me the following error at every action. The URL in config.php is the same and I included the .nginx.conf file in my nginx configuration, but it didn't help.

The /storage/logs folder and the browser console are empty and I'm using a Debian 11 VPS with PHP 8.1. I tried to follow several posts in this community with a similar problem. But didn't help.

Thanks in advance and have a nice day.

feds have you set the right URL in your config? Also did you include the nginx.conf of Flarum?

GreXXL Hello 🙂

Yes, the URL in my config is the same that I use to navigate into the main forum page: https://mydomain.com/forum/public/. At the moment, I didn't changed any option in the config. I also included Flarum nginx.conf in my configuration

I just tried to do a clean installation, but it still doesn't work.

Copy and paste your output of php flarum info
Can you follow the following articles carefully and make sure you got everything set up correctly.

Those errors tend to be from incorrect server configs/ settings.

UPDATE: I removed the /public/ slug on my URL following this guide: https://docs.flarum.org/install/#customizing-paths

Now Flarum works on the correct URL. But the error "This resource was not found" still persists. This error persists on every action I try to do. I cleared the cache using php flarum cache:clear.

I also changed my site url in config.php but there's no way I can login or make anything.

If I look to my nginx log file, I see those errors from my WordPress Installation 🤔

feds according to your php flarum info output, your webserver does not load the required modules as per our installation guidelines: https://docs.flarum.org/install; please make sure to load the necessary PHP modules.

luceos

feds the error you are mentioning is caused by wp-includes, this is part of a Wordpress installation not Flarum.

If hitting your Flarum installation causes you to see a "This resources was not found" error then it's almost always an issue with rewrites not being configured. To resolve this, you will need to configure the nginx server configuration block for the Flarum install to include the nginx config block that is inside the Flarum installation path.

Please share your nginx server block for the Flarum installation so that we can trace the issue further.

feds

GreXXL please make sure to load the necessary PHP modules.

I have all the required PHP extensions. I also tried to restart them or use a different PHP version only for Flarum. But I guess that's an nginx problem like @luceos said 😥

Hello, I followed the documentation. If I followed correctly, I included the .nginx.conf file in my nginx configuration.

After including the flarum .nginx.conf file in my server block, I moved all the /public content to the flarum root folder (e.g. mydomain.eu/forum).

I really don't understand what am I doing wrong

fakruzaruret

feds why you did not add filepath of flarum subdirectory to nginx file?

May be this effect

location /forum/public {
try_files $uri $uri/ /forum/public/index.php?$query_string;
}

feds

fakruzaruret Now it worked! Thank you very much 🙂
