[SOLVED] After upgrade to 1.6.0.7, Can't log in to B.O...

[tatamimi]

Hello!

I'm testing to upgrading from 1.4.0.17 to  1.6.0.7.

At first after upgrade, the log in page was all blank(white)...
I found it was the problem of php version (if PHP version is under 5.3, It doesn't work) so I changed the PHP version to 5.4.

 

After that, I can access the log in page but even I wrote correct ID and Password, I can go to next page but it is all blanc(white)...

I putted this code in .htaccess

php_flag  display_errors On

and try to know the error code,

The blank page is like this...
 

 

Not Found

The requested URL /installfolder/admin---/&token=924327367031631d------
was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

 

 

I tried to clear cash but it's still blank...

Please help me!

Enable error reporting as described in my signature instead of using htaccess. Then erase that (htaccess), rename the admin folder to something without dashes and try accessing again

Thank you Nemo1!

I erase the code in .htaccess and use the code of debag (in the /config/define.inc.php ).

I found there are some missing table of database, and some old module cause problems...

When I used 1-click upgrade module, I checked to use old template and checked "no" in "Disable non-native modules" ...
I think that causes many problems...

Now I retry upgrade again from the beginning, I used 1-click upgrade module but this time 
 

Disable non-native modules　 > Yes
Upgrade the "default" theme    > Yes

In my case, I could finish upgrade.
(There are still many problems... but I can log in now and can modify maybe...)

Thank you a lot!
