MyBB Community Forums

Hello,

I upgraded from mybb 1.6 to mybb 1.8 and did NOT backup my files/db. I performed the upgrade using softalucous through Arvixe.com. I now know that was a big mistake. Anyway, i hope that someone can help out. Here are my errors:

1) When I try to login as forum admin, I get this error:

MyBB SQL Error
MyBB has experienced an internal SQL error and cannot continue.

SQL Error:
1054 - Unknown column 'useragent' in 'field list'
Query:
INSERT INTO xywna_adminsessions (sid,uid,loginkey,ip,dateline,lastactive,data,useragent) VALUES ('d64abef41703f8a06564b17fc701d72f','1','JX8rXF4Tc8yciPF8qcXKy53q56j6rLIWvswgCS8qQAG6DgaXnf',X'621111c3','1411507325','1411507325','a:0:{}','Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.120 Safa')


2) When I go to the homepage, i get these errors (and the display is messed up, almost like there is no CSS file):

The following warnings occurred:
Warning [2] Invalid argument supplied for foreach() - Line: 331 - File: global.php PHP 5.2.17 (Linux)
File Line Function
/global.php 331 errorHandler->error
/index.php 18 require_once


3) And, when I click on a forum category, I get this error:


MyBB SQL Error
MyBB has experienced an internal SQL error and cannot continue.

SQL Error:
1054 - Unknown column 'deletedthreads' in 'field list'
Query:
SELECT threads, unapprovedthreads, deletedthreads FROM xywna_forums WHERE fid = '12' LIMIT 1

So, any and all help is greatly appreciated! Thanks!!!

It seems your database wasn'nt upgraded, only the .php files were modified.
Peharps you can save everything and try upgrading using the normal way.
