Installation Error - White page/screen after DB is created

[Ryan@SwiftKey]

Hi,

I'm trying to install IPS V4.0 Forums onto my server (running Ubuntu 14.04).  Once I've done the initial setup (all checks were passed), after the progress bar completes and the database has been installed/populated, the page refreshes (without the progress bar reaching 100% completion) and I'm taken to a blank white page, URL path is: /admin/install/index.php?controller=install&mr=["3","core"]

It stays blank. If I go back to my home URL, I get the following error message:

An error occurred (500 Error)

We're sorry, but a temporary technical error has occurred which means we cannot display this site right now. 

You can try again by clicking the button below, or try again later. 

Try again

 I've tried changing perms on all files and folders to 777.  I've also looked at the apache error logs and found the following:

[Thu Jan 22 14:56:57.899508 2015] [:error] [pid 10340] [client 86.188.229.98:5323] PHP Fatal error:  Class 'IPS\\core\\extensions\\core\\FileStorage\\._Theme' not found in /var/www/html/system/Application/Application.php on line 567, referer: http://mysite.com/admin/install/index.php?controller=install&start=1

Any ideas?

An option is to go to init.php, find the exceptionHandler function and then add to the beginning of it var_dump( $exception );exit; .  This would output the actual exception or error that is being thrown.

Thank you bfarber.  Here it is.

I would log a bug for this, it may be overlooked in the forum.

[bfarber]

It's trying to set an invalid or non-existing group - I can't reproduce this.

[tbar]

I have the same error message and code, but not the type that can go into the code and make any changes. :(
