Fatal error after importing database
I have tried moving my Vanilla (ver. 2.1.8p2) forum to a new server. I used phpMyAdmin to export the entire database and imported it to another host. After that I made a fresh Vanilla install (ver. 2.4.201) using the hostname, user etc. from the new server. When I tried to open the forum for the first time with index.php I got the following warning:
Fatal Error in Vanilla\AddonManager.autoload();
The error occurred on or near: /var/www/naturnettet.net/public_html/fracom/applications/dashboard/models/class.usermodel.php
4934: * Checks if a url is saved as a navigation preference and if so, deletes it.
4935: * Also optionally resets the section dashboard landing page, which may be desirable if a user no
This is followed by a list called Backtrace and Additional information for support personnel
Unfortunately, I am unable to understand what to do in order to make it work.
Can anyone here help (I can copy/paste the additional information) or is the old database incompatible with the new Vanilla forum?
