Solved Internal Server when creating new Topics - no problems (when deleting topics)

Hi,

We're running Kunena 4.0.3, and Joomla 3.5.1 on ubuntu 14.04.4 with 4 gb of ram and 4 cpu cores. The system uptime almost always shows less than 1 gb of memory use, and very low load averages (.03 at the moment).

Creating a new topic on Kunena is timing out, and displaying Internal Error. Apache logs indicate:

FastCGI: comm with server "/usr/lib/cgi-bin/php5-fcgi" aborted: idle timeout (30 sec), referer: https://(site)/forum/newtopic.html

and

FastCGI: incomplete headers (0 bytes) received from server "/usr/lib/cgi-bin/php5-fcgi", referer: https://(site)/forum/newtopic.html

If I go back to the forum, I can see that the topic actually got created - but the bottom of the webpage says, "Waiting for hostname....)

We recently switched from Apache2 handler to fastCGI, and I'm wondering/suspecting that I haven't set it up properly. It always has taken a while to create a new topic (definitely more than 10 seconds), but it didn't used to time out.

Thanks in advance for any help you can provide.

Here's our configuration:

Hello,

Can-you please update Kunena to 4.0.10 version ?

Sure - though I wasn't notified that that was available.

I just tried to get Joomla to find the update to 4.0.10, but it wasn't available. I'll hunt around for documentation on how to install it manually.

You can install it like any other extension. www.kunena.org/download
Please create a backup before.

Thanks - went along that route, but got the notice that the upload file was too large. I'm going to edit php.ini and try again.

I keep getting this error:

Error

There was an error uploading this file to the server.
Maximum PHP file upload size is too small: This is set in php.ini in both upload_max_filesize and post_max_size settings of your PHP settings (located in php.ini and/or .htaccess file).
Unable to find install package.

I edited /etc/php5/apache2/php.ini and set the upload_max_filesize = 3M. The max post size is already set to 8M, and this package looks to be about 2.1M, so that shouldn't be causing an issue.

BTW - I haven't installed components before (someone else on the team has done that in the past). I didn't unzip the .zip pkg file. Is that the correct way to do it? Should I move it to docroot/tmp/ and install from there?

Thanks,
M

Do-you have restarted apache after that you have edited the php.ini ?

I had two issues that kept me from installing it. I failed to edit the correct php.ini file (I needed to us /etc/php5/fpm/php.ini, and I had failed to restart apache2 and php).

It installed correctly now, but I'm still getting the same error:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at [no address given] to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.

and in apache2/error.log

As I said earlier, it's always taken a while to create a new post (many times longer than deleting one), but it didn't used to time out. We have moved to fastcgi recently, and that's when the timeout error cropped up. We've been advised to run joomla with fastCGI, so I'd like to be able to get Kunena to work with FastCGI.

Thanks - I've got to go offline for about 45 minutes, but I'll be back then.

Try to enable debug mode in Joomla! and Kunena to see a better error message

I'm tailing the /var/log/apache2/error.log while I create a new topic. I don't see anything happen when I first press the submit button. However, the page just hangs there, saying, "waiting for host." Then, the 500 error occurs at the same time as the following lines are written to the log:

[Thu May 05 11:32:56.135087 2016] [:error] [pid 8987] [client 192.168.250.2:55524] FastCGI: server "/usr/lib/cgi-bin/php5-fcgi" stderr: PHP message: PHP Warning: mysqli::stat(): Couldn't fetch mysqli in document root /libraries/joomla/database/driver/mysqli.php on line 219

I'm seeing errors all over the page, but they appear before I actually get the error that led me to the forum. They appear as the page to create a new topic loads (but not as it gets submitted):
