Error 500 in discussion

jasilva

Hello guys I new use vanilla (in fact today download it!), I cant install and configured all, its very easy, but when I create a new discussion I get a error 500

I use a Centos 7 Server, with Apache 2.4.6 and vanilla 2.2 all other features works well, but I cant see a discussion, including that comes by default.

In other post I read about debugger, I activate Debugger By Mark O'Sullivan and download Kpr - Krumo Print Debugger By Debra Venckus, but I do not know how to see the error in the log

The URL is index.php?p=/discussion/3/hello

Welcome to the community.

With debug turned on, when you try to visit a forum page, Vanilla will show you details of the error it encountered.

I don't think a 500 error is a Vanilla issue.

You need to look at your web server error logs.

If you don't know how to do that, contact your web host for help.

Thanks for your reply.

When I visit any page a can see the log in the bottom of the page like:

Debug Information
Canonical Url: http://192.168.122.1/vanilla/index.php?p=/categories
8 queries in 0.038735866546631s

But In discussion I get a Blank Page in Firefox, and error 500 in Chrome, for example when I visit this URL

/vanilla/index.php?p=/discussion/4/test?new=1

Please post the contents of your htacess file

jasilva

The file is in this position

/var/www/html/vanilla/.htaccess

And contains

# Original
# If you modify this file then change the above line to: # Modified
<IfModule mod_rewrite.c>
   RewriteEngine On
   # Certain hosts may require the following line.
   # If vanilla is in a subfolder then you need to specify it after the /.
   # (ex. You put Vanilla in /forum so change the next line to: RewriteBase /forum)
   # RewriteBase /
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteRule ^(.*)$ index.php\?p=$1 [QSA,L]
</IfModule>

Change the file to this, and then check config.php for this line, report after what happened.

$Configuration['Garden']['RewriteUrls']= TRUE;

# Modified
# If you modify this file then change the above line to: # Modified
<IfModule mod_rewrite.c>
   RewriteEngine On
   # Certain hosts may require the following line.
   # If vanilla is in a subfolder then you need to specify it after the /.
   # (ex. You put Vanilla in /forum so change the next line to: RewriteBase /forum or the name of subdirectory)
    RewriteBase /vanilla
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteRule ^(.*)$ index.php\?p=$1 [QSA,L]
</IfModule>

Ok I change the .htacces file, and conf/config.php file $Configuration['Garden']['RewriteUrls']= TRUE; no exist so I add and restart the apache server. But I get other error

Present same error Not found

Is your forum located in /vanilla ?

Look inside the CGI logs from the server to look at the errors…

You must have some kind of misconfiguration in the the database or something like that.

I found new information:

When entering discussions url Centos send me an SELinux Alert:

The source process /usr/sbin/httpd
Attemted this acces: getattr
On this file index.php 

In the alert are many different files, for example

The source process /usr/sbin/httpd
Attemted this acces: read
On this file localise.xml 

The source process /usr/sbin/httpd
Attemted this acces: write
On this file a_dashboard_library_map.ini

The source process /usr/sbin/httpd
Attemted this acces: write
On this directory /var/www/html/vanilla/cache

The source process /usr/sbin/httpd
Attemted this acces: remove_name
On this directory 70211851556c23d787d976.tmp 

What happen? I apply the permissions to folders in the tutorial
