Hi!

I had the same problem today.

Solution: Just go to Fotorama settings page and click "Save Settings" button (no need to change anything).

Reason: The new settings (in this new version) variables are probably not initialized to default values during update. Saving did that.

Hope it helps you.

UPDATE: Yes, it seems they forgot to add a code for initializing of the new settings. I would solve it by adding something like this to main.inc.php to Fotorama_init() function:

  // Upgrade params from 12.b
  if (!isset($conf['Fotorama']['mobile_backend'])) {
    $conf['Fotorama']['mobile_backend'] = 'fotorama';
    $conf['Fotorama']['desktop_backend'] = 'fotorama';
  }

UPDATE 2: I also had the problem that after starting the slideshow it took very, very long time until it really started (and browser seemed to be hanging). I solved it by changing "$split_limit" in main.inc.php from 4000 to 400 (just like in previous versions). Don't know why they changed it...
