I am updating my 4.7 page to 6.3, but there are some problems. Update to 5.8 went without any problems, the page works very well. But when I try to update to 6.3, I get this error and the updater won't run:
Warning: Unknown column 'language' in 'where clause' query: SELECT src FROM url_alias WHERE dst = 'node' AND language IN('en', '') ORDER BY language DESC in /home/*myaccount*/public_html/includes/database.mysql.inc on line 128
If anyone could help me to solve it, I would be very grateful. I am sure I followed the update inscructions correctly (turned modules off, etc..) - I already tried it many times just to be sure, but it still doesn't work.
I am aware this problem has been mentioned several times already. I searched the Forums, but didnt find the definite answer though. Someone provided a link to Language Subsistem which might solve the problem, but I didn't install it yet because (a) I am still unsure if it relates to my problem, and (b) the Subsystem is from 2007, while the newest version of Drupal is from 2008... I was afraid using the old files would result in more problems.
