No Navigation menu after upgrade from 5.7 to 6
Hello Drupal Experts,
I am somewhat of a newbie to Drupal and I am desperately in need of your expertise for the problem that I am having. I am performing this upgrade on a test server (Windows 2003, MySQL 5.0.51a). Currently I am running Drupal v4.7.3 with PHP v5.1.4 I have followed some of the suggestions for upgrading to Drupal v6.0 from the posts here. Below are my steps, and I also follow the "upgrade.txt" file instructions, making backups for each versions steps.
0) As for Themes, I use the "Bluemarine"
1) Disable the following contributed modules (EasyLinks, Biblio, Job) as I no longer use them
2) Drupal upgrade steps 4.7.3 --> 4.7.11 --> 5.0 --> 5.1 (* with PHP v5.2.1) --> 5.7 --> 6.0
* At Drupal v5.1, I upgraded my PHP v5.1.4 to PHP v5.2.1 as I believe that is a requirement for Drupal v5.1
The upgrade process all went fine, no errors at all. The website looks fine after the upgrade from version v4.7.3 through v5.7 but when I upgraded from v5.7 to v6.0 the navigation menu (the left side menu) does not display at all. I also tried upgrading to v6.1 and still the navigation menu (the left side menu) does not display at all.
If anyone know how to resolve this issue that I am having where the navigation menu (the left side menu) does not display after upgrading from v5.7 to v6.0 would you please help me.
Thank you,
John

No navigation menu after upgrade from v5.7 to v6.0
Hello Drupal Experts,
Has anyone out there encounter this particular problem at all?
No navigation menu after upgrade from v5.7 to v6.0
Hello Drupal Experts,
After many hours and of looking through the code trying to figure this out and many thanks to a very good friend who happens to be a web developer he said to look in the code that generates the navigation menu. I took his advice and started looking and it turns out it is in the page.tpl.php page that is in my theme folder (bluemarine folder). I had my original page.tpl.php open and also had the page from v6.0 open and I found the code that is different in v6.0 then my original page.tpl.php.
The difference is;
My original page.tpl.php - one of the line has
<?phpprint $sidebar_left
?>
v6.0 page.tpl.php - has
<?phpprint $left
?>
I changed it to my original page.tpl.php line to
<?phpprint $left
?>
Well, I hope this helps for those in the future that might have this issue.........
Good Luck,
John
