photocrati on "[Plugin: NextGEN Gallery] Gallery order in album doesn't work"

G'day,

I will start with the questions, asked in the sticked thread.

Q: WordPress up to date?
A: Yes
Q: NextGEN up to date?
A: Yes
Q: What version of NGG did you upgrade from?
A: From last to current

Q: MySQL up to date (at least 5.0)?
A: Yes (5.5.46)
Q: PHP up to date (at least 5.2.4)?
A: Yes (5.6)
Q: The mod_rewrite Apache module activated?
A: Don't know. (How to check? What is it?)
Q: PHP Safe Mode OFF?
A: Don't know. (How to check? What is it?)

Q: Who are you hosted with?
A: HostEurope
Q: What theme are you running?
A: Evolve
Q: Which plugins do you have installed and activated?
A: - Akismet
- All in One SEO Pack
- Hello Dolly
- Image Widget
- Page Builder by SiteOrigin
- Page Views Count
- Redux Framework
- WP Google Maps
Q: Does this error still occur if you switch your theme to a WordPress Twenty series theme and deactivate all plugins except NextGEN Gallery? (please be sure to clear your browser cache and reload your site after deactivating)
A: Yes, error still occurs.

And now here is my error:
I can't sort he galleries inside an album. It doesn't matter what I choose in the "other options" -> "standard sorting" (I tried date/time, ID and costume), the sorting doesn't work. If I change the sorting in "manage album" the sorting on the page changes but not like I sorted it. It can't figure out a system, it looks like that the plugin is changing the sorting randomly if I change something in manage album.

Thanks for reading.

Regards
Flo
