I first tried to do a manual install, from an up to date drupal (drupal 7.38, media 2.0 beta1) :
1. There are 3 modules not availaible from the drupal site : custom, md_pricing_table, springspray. I guess it's all megadrupal material needed for the theme ? It would have been easier to understand with one megadrupal module, no ?
2. I got a wsod going to the preference page of the theme : "Fatal error: Call to undefined function media_browser_js() in /xxxxxx/sites/all/themes/md_springspray/theme-settings.php on line 16". I managed to get over it, adding a media_browser_js() function in sites/all/modules/media/includes/media.browser.inc I found in the drupalcontrib site  !?
3. I could then access theme preference page but changing logo was impossible. I found a "TypeError: $(...).on is not a function" preventing theme script.js to work ok... then troubles with jquery migrate ... enough.
4. I installed the 'installation profile' with no problem. Site working. But security upgrades was needed. Did them. Site stop working with same error (in 2.) !
Could you help ?
Sorry for english errors, I'm french.
