(Solved) ERROR 500 - Internal Server Error!

Hello,
I can open the GUI for ISPConfig3 no problem but after installing WHMCS cannot open the admin page and I am getting the below errors.
/var/log/apache2

var/log/suexec.log

One thing I have done that is I have changed the server name after finishing off the setup of ISPconfig3, that may have caused this problem. Could not run the setup of ISPConfig3 again to make the RSA match the server name but never reach the step where I can recreate the SSL.
Help please.
Thanks,

 

Have you checked apache2ctl -S if the vhost for ispconfig is still intact and not overridden?

 

The output of apache2ctl -S shows the latest server name correctly but I see the following and I am not sure if it is an error or it is normal.

One of my problems now is the ssl for ISPConfig3, how do I reconfigure it like what you do during setup? I tried update and new install but the script refuses to run since I have the latest version.

 

The NameVirtualHost message is not a problem, it's normal
To run the update again, you have to download the tar.gz package from http://www.ispconfig.org/files/file/2-ispconfig/
Extract the package, go to install/ inside the extracted directory, then run php -q update.php

 

Thanks for the quick response,
But the update script never runs not sure why?

Thanks,

 

Thanks again,

I think I messed up something since

And the browser shows php info as
"PHP Version 5.5.9-1ubuntu4.9"
Thanks,

 

I am going through my notes and I think i was trying to install two versions of php and it did not work.
Is there a way I can remove / uninstall all PHP and then start fresh install to the latest and that is it.

 

Thanks again,
which php

 

there is no php under /usr/bin

 

My problem is I can cd to /usr/bin but cannot get to php although I see the folder.

 

What till said is you have to go to the folder where you extracted ISPConfig. Let's say it is in /tmp/ispconfig3/
Just go there

Code:

cd /tmp/ispconfig3/install/
/usr/bin/php -q update.php

 

Wow the two of you are amazing.
Thanks a million.
