Hello,
I successfully upgraded from 4.7.6 to 4.7.11 to 5.0 then to 5.7. Then I decide to upgrade from 5.7 to 6.0.
When I did the update.php proper, I got a page saying register globals had to be disabled. So I searched this website and found out I had to add this to .htaccess: AddType x-mapp-php5 .ph
.
I did this (I knew it worked cause I used it on a previous upgrade).
Then instead of clicking on the "continue button" I reloaded the page so the modified .htacesss file would be taken into account. Was that a mistake?
Then I got a lot of mysql warnings, and I thought perhaps reloading was the cause, so I ran update.php again (I've read you shouldn't do that but I didn't know what to do).
I got no error warnings, just the update button, so I cliked on it.
Then I got a lots of warnings. Here they are:
* user warning: You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near 'SELECT vid FROM node n WHERE t.nid = n.nid)' at line 1 query: UPDATE term_node t SET vid = (SELECT vid FROM node n WHERE t.nid = n.nid) in /homepages/xxx/htdocs/modules/system/system.install on line 1154.
