Check server logs for errors.
Same issue on my installation.
I just wanted to upgrade from 3.4 to 3.5 (to get to 3.6 finally).
There server.log seems to be normal, but in the wrapper.log I found the following error (several times):
INFO | jvm 1 | 2016/07/11 10:29:33 | liquibase.exception.DatabaseException: Table "GROUPS" already exists; SQL statement: INFO | jvm 1 | 2016/07/11 10:29:33 | CREATE TABLE PUBLIC.groups (id INT AUTO_INCREMENT NOT NULL, name VARCHAR(128) NOT NULL, groupid INT, CONSTRAINT PK_GROUPS PRIMARY KEY (id)) [42101-191] [Failed SQL: CREATE TABLE PUBLIC.groups (id INT AUTO_INCREMENT NOT NULL, name VARCHAR(128) NOT NULL, groupid INT, CONSTRAINT PK_GROUPS PRIMARY KEY (id))]
What does your current database schema look like?
By the way, you don't need to update to 3.5. You can update straight to 3.6.
not sure how to access the database schema....
Anyway, I "fixed" it by starting with a clean database. I think there was some problem because I tried the alternate UI which is available in the web.
Thank for your quick response.
It would definitely conflict with alternative UI mod.
Hello,
I'm just getting started with the software. When I start the Traccar Service it stops on it's own a few seconds later. And the localhost page doesn't load.
How can I solve this problem ?
I'm on windows 7 64 bits.
Thank you Anton
