Problems after installation

Installing 3.6 on Ubuntu 16.04

The first problem I encountered was that the index page was breaking with no output after the opening tag of the languages dropdown.
Commented out the line calling getLanguages() and uncommented the list of langs on the line below.
Then the index page loads completely.

Now I have created projects, but when I try to edit them the popup does not load - I just see the loading gif. /xerte/edithtml.php?template_id=1
No errors in the browser console, no errors in the xerte log or the server log.

Any ideas as to how to get the editor working or how to find out what is breaking would be much appreciated.

Thanks!

This seems like a dependency isn't being met, but I have all the dependencies listed.

Do you know of dependencies which aren't listed?

Or of wider requirements list?

Thanks

I would guess that a dependency problem would be visible in the server (apache/php) log.

You could try to set $developer to true around line 43 of config.php.
