Contao 3.5.9

I am getting a 500 server error in my contao website. This occurs intermitently on every page. error_log shows the following:

xxx.xxx.xxx.xxx - - [29/Apr/2016:11:08:39 +0000] "GET /news-insight/news.html HTTP/1.1" 500 - "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.112 Safari/537.36"

PHP log shows nothing.

I am using the default htaccess file

Has anyone come across this before? How can it be fixed?

You can give us more information, what is your OS? which version of PHP you are using? maybe look at system/logs/error.log in your application root and search for a corresponding entry. – Loqman
Also try to enable the coreOnlyMode by putting $GLOBALS['TL_CONFIG']['coreOnlyMode'] = true; in your /system/config/localconfig.php and then test again. If the error does not happen again, an extension is probably at fault. – fritzmg
