HTTP 500 internal server error on Default Page

Hello,

after installin MJ 1.2.5.1 in Joomla 3.0.3, the Default Frontpafe isn't working any more.
Just getting an HTTP 500 Error.

Using Template Alrounder 1.1. But also with Beez3 its not working.

When disabling the MJ site Plugin, its working again.

Do you now about this issue?

Thanks
Christian

What do have in error_log?
We have tested MJ 1.2.5.1 in 3.0.3 and 3.1b2, and it worked correctly in both cases.

There are no entries in apache logfiles or syslog.
When i use Firefox, i just get a blank page.
When i use IE9, i get HTTP 500.

Test URL is hummel-web.at/joomla3

Maybe you have separate php's error log (check website's document root directory).

/var/www/vhosts/hummel-web.at/httpdocs/joomla3/plugins/mobile/scientiaDSscientiaDSTeraWurflConfig.php does not exist

i have disabled scientia plugin and enabled AMDD.. so it works.
looks lke scientia isn't Joomla 3 compatible

Edit: scientiaDSscientiaDSTeraWurflConfig.php should be scientia/scientia/TeraWurflConfig.php i think.
That file would exist

Thank you for this report, we will fix Mobile-Scientia plugin soon.
