@Febian This mean you need to install all neccesary software components on your server and after that just copy databasefiles & the nodebb files to it and fire it up.

@Febian And you have a Nodebb already installed on the destination system ?

@Febian What kind of customization have you done ? Did you changed file or data on the database ?

@julian There is no apostroph on my side.

I have the same Problem. I logged in Yesterday and let the Browser open, then this morning i had to relogin, so i clicked on Login ...:

I had to reload the Page (F5) to get into.

tapatalk is for most plugins a problem. I had it on mybb running and disabled it be course of that.
Best deal is if the forum supports Mobil directly.

@TaLoche You run into a known Problem, it is fixed on nodebb 0.6 but not in 0.5x. Please change the following file

Find this file NodeBB/src/groups.js LINE-454, change
From
if (err) {

To

if (err && err.message !== '[[error:group-already-exists]]') {

Kill nodebb before. And then just re import. Thanks to @bentael for this solution.

@TaLoche Did you saved the Log Files to the Server ?

@TaLoche It was the soft delete option of Mybb1.8. I removed it. Just Upgrade the import plugin and you are fine.

But it all has a price... :

@TaLoche No need for a dump. Give me 10h to check it out.

@TaLoche They change a few fields from 1.6 -> 1.8. I can give you a modified export if you like. It's not a big deal. The accents should not be a problem.

@TaLoche Which Version of mybb are you using ?

@TaLoche You need to create the database & user first, then:
mysql -u USERNAME -p DATABASE < file.sql

Just saw that a_5mith already gave you a answer.

@trevor yes. But it should be a standard function.

@trevor The second column: http://www.vbulletin.org/forum/forumdisplay.php?f=13

Nodebb is based in nodejs

@Sloppier-Kitty nodejs installed ? npm is usualy part of the nodejs package.

@Peter-Zoltan-Keresztes Im usually lazy and just copy the database files from one to the other

have you set "domain for session cookie" ? this can course this kind of trouble.
