I got "HTTP ERROR 500" on webpage but no error log found

Postby baijianpeng » Thu May 11, 2017 11:06 pm

My server was built with VestaCP v0.98-17 over Ubuntu 16.04. My website was built with Joomla CMS (updated to latest 3.7.0 ).

Today I tried to update a download file in the Remository component of my Joomla installation. When I click on "Save" button at the backend of Joomla, I got following error message:

HTTP ERROR 500


There is no further error message, even after I enabled Error Reporting of Joomla to "development". So I have no idea what caused this 500 error.

Then I login in SSH terminal and tried to find out the corresponding error logs. But there is no records in this time in following files:

Code: Select all

/var/log/apache2/access.log (empty file)
/var/log/apache2/error.log
/var/log/apache2/domains/joomlagate.com.error.log

/var/log/nginx/access.log (empty file)
/var/log/nginx/error.log (empty file)


The folder "/var/log/nginx/domains" is empty.

Now, how can I know why there is such a "500 error" when I trying to save a file in Remository at Joomla backend? Which log file on the server should I look into?

Thank you.

500 server errors are 99% of the time caused by incorrect file permissions / ownership or a problem in your .htaccess file.

I'd check those as your first step.

That "download" item in my Remository component is a "remote download", means that there is no file needs to be saved to my own hosting server, just text data need to be saved to Database tables.

I have no idea why Remository won't save that file.

Thank you.
