error stops me from accessing website

Hi,

I have setup ISPConfig with several Joomla websites.
I am migrating some websites, but with the 4th I have stumpled upon an error which I can't figure out to solve?

When trying to reach the site www.bijzondervastgoed.nl I get an internal server error 500.

The setup is similar as another migrated site and I have checked the two configuration.php files and they are similar. (except for database and user)

When checking the Apache error log I find the follwoing messages.

The unknown filter error I found how to solve on the forum so I followed the instructions. (maybe the gracefull restart indicates this has been solved)

any hints?

So the an unknown filter was not added: PHP error is gone now?
Have you tried to update your system?

Code:

apt-get update
apt-get upgrade

 

PHP is not gone, as I have other websites on the same server that run well.

I updated and upgraded but nothing besides Release.gpg was fetched.

 

But is the "an unknown filter was not added: PHP" error gone now?

 

Hi Falko,

the unknownb filter message has disappeared also.

Weird, but is is gone

Do you still get the internal server error 500?

 

The error 500 has also disappeared. Somehow deleting the website with ISP config and setting it up again did the trick.

Could have been a mismatch in the export of the old SQL database to the new database.
That is the only thing I can imagine what could have caused the problem.
