Internal server error 500

Hi, I have several problems relating to performance of my site. It's come to a point where it's virtually impossible to reach my site, let alone work on it. What happens, is I can work on my site for about 3 or 4 minutes, then it gets extremely slow and shortly after that, it doesn't respond at all anymore until I get an Internal Server Error 500.

I really hope you can help me.

My config:
PHP Built On Linux srv047158.webreus.nl 2.6.18-028stab070.2 #1 SMP Tue Jul 6 14:34:09 MSD 2010 i686
PHP Version 5.3.10
Web Server Apache/2.0.54 (Fedora)
WebServer to PHP Interface cgi-fcgi
Joomla! Version Joomla! 3.1.1 Stable [ Ember ] 26-April-2013 14:00 GMT

Template: Gavick Simplicity J3
Components: K2, Akeeba Backup, Admin, ARS and Subscriptions

What I checked:
Error logs
I checked the server error logs. There are a lot of these errors: Premature end of script headers: php53.fcgi
I’m no expert, I don’t know what that signifies.

Google page speed
I checked the site (http://www.byimke.nl) @ Google page speed https://developers.google.com/speed/pagespeed
it suggests two problems with the highest priority:
1. Enable compression
I enabled compression in the template advanced settings. It broke my site’s layout completely, so I had to disable it again.
2. Enable browser caching
I enabled both cache options in the template backend (“Use GK cache” and “CSS cache”), but disabled the cache option in the Joomla Global Configuration – System as per the advised settings in the Gavick forum. I also enabled the cache plugin and enabled Browser caching (see https://www.gavick.com/forums/security-and-configuration/recommended-options-in-the-templates-settings-for-cache-21667.html?p=105759&hilit=gk%20cache%20gkcache#p105759).
After that, Google page speed still tells me to enable browser caching, so somehow it doesn’t pick it up. Also, it suggests to set the cache time to a week. I set the cache time in the Joomla cache settings to 10080 minutes, as the post I just referred to says that GK cache takes it’s parameters from the Joomla cache settings.

Hi,
Our gk_cache script is a little modification of default joomla one. So please add your changes to our script. And about second one yes script takes expired time paramtere from joomla.

It still tells me to set it to a week, so somehow that setting doesn’t get picked up either.
I don’t know what to do next. I’m at my wits’ end. I really hope someone can help me.

Before doing anything you should check following as your site is being marked as attack site by google.

This suggests your site or server maybe still infected or was infected.

See you around...

Thanks, I missed that Google report. My old Joomla site was hacked a while ago. I've cleaned it up and am building a new site, so there's no malware anymore, so this shouldn't have any effect on the problem. I've just submitted a request for verification by Google.

Have you contacted your host regarding slow downs or time outs. Error 500 is a very generic error so it could be many things. Mostly server cannot handle your request which usually suggests server resources are low or if this a shared hosting another user might be using most resources.

You can install a standard joomla package from joomla itself and monitor this for few days to see whether problem is with your hosting server.

Hi Norman,

I have the feeling that's not it, because it really always takes a few minutes of me working on the backend before slowing down. Have you seen the Google Page Speed report? It suggests the problem is with the installed site, not the server.

I'll try your suggestion though and let you know.

Cheers,
Imke

I've tried finding this package, but I haven't. I've only found a third party extension (http://extensions.joomla.org/extensions/hosting-a-servers/servers/11977) which is not compatible with my version of Joomla. Could someone point me in the right direction please? Thanks!

Seems I wasn't clear

I meant for you to download normal joomla from joomla.org and install that to see if you are having the same problems you have had. If you do then the problem is with your hosting server.

Download any one of the below files and install it in a sub-domain please. I am not sure which version you have tried so below are links for both j2.5x and j3.x.

Google does not spend more then few seconds while testing, real experience comes down to your experience. Have you asked your host if there are any problems with your server or your account?

Let us know, see you around...

Let me know how you get on.

Thanks for the fast reply Norman. I did the installation with standard Joomla package and then I installed the template, not the quickstart package, so there shouldn't be a difference. I think I'll take your suggestion and tweak it a bit In a bit I'll set the site to a different template and see whether the problem still persists.

I've several sites on this host, all performing well. The first thing I did, was check the hosts reports. The last problem they reported was solved on April 17th, so that shouldn't be it.

Well from time time things do happen with hosting servers

Please simply play around with standard joomla template for test purposes. If you want to develop your site you can download Xamp or Wamp and install it in your local computer. This way you can be quicker creating items / content / design etc, Once you finish your design and content, you can then upload to your remote server and do your final checks to be sure everything is in good working order.

See you around...

I've fixed this issue by installing RokBooster extension.

Thanks for letting us know, I ll keep that in mind, see you around...

I am getting internal server error 500 when I try to log in as admin. Using latest Joomla and installed GK creativity using Joomla 3.0. Any help appreciated.

Double post, continuing on other topic.
