Looks like your CSS files are somehow missing.
Try to upload some theme and check if it works.
Can we get your forum url to check it out?
thanks @Ikerepc for answering me
i solve this buy using same db as table backup name
but now i hade this problem about avatar its like all gone and when i try to change avatar i have broken pics
[attachment=39871]
[attachment=39872]
below try to chose them and you will see the orginal problem
my web : www.vm-clan.org
update :
avatar is ok after i run
UPDATE mybb_users SET avatar='', signature=''
but problem of changing avatar still existed
FIXED
just for ppl if they come from the future
i tried a lot to make it but no one help me specially icyboards support they tell me we they are don't support out icyboards so i search a lot and there is nothing talking about move forum to my host with icyboards backup
anyway
what you need to do is make new mybb forum and go to your db and import your icyboards backup now you have 2 db don't worry now delete all mybb tables and leave those i mention at pic below
leave these tables i mention with black squire
so now you have only
mybb_themes
mybb_templatesets
mybb_templates
mybb_templategroup
mybb_settings
from installed mybb forum
now you have to rename all your icyboeards forum tabels EXCEPT those i like pic i add above
how you do this this : easy
now you done with your db
now you have some problems (the main problem) you need to do upgrade to your forum to make it right
go to install folder and delete lock file and do upgrade
https://yourdomain.com/install/upgrade.php
done
maybe you can't access to your adminCP
Go to mybb main folder go to inc open setting.php
change this to your domain
$settings['cookiedomain'] = ".vm-clan.org";
done
PS : sorry for my bad english just want to share some help for other ppl cuz i tried like week to make this work and i can't find someone to help me so i want help others
best of wishs
