Hi

I'm in the process of upgrading a site, but it's all gone horrible wrong.

The site currently runs Drupal 4.6.5, and I want to upgrade it to the latest version - but I want to do this on a separate server for a number of reasons.

I've tried moving it, but the output is garbled, e.g.

{head} {styles}
{_BLOCK_.header.logo} {_BLOCK_.header.site_name}
{secondary_links}
{primary_links}
{_BLOCK_.footer.blocks}
{_BLOCK_.node.title} {submitted}
{content}
{_BLOCK_.node.title} {submitted}

This is not as expected.

Hi there,

When I try to submit a forum topic, I'm unable to select to which forum the topic belongs. The whole taxonomy part of the submit-form has gone. All forum-categories do exists thought, but they won't appear on the forum submit form. I only have a title and a body field.

I tried uninstalling the forum and reinstalling it, but that didn't solve the issue.
Recently I upgraded from 5.1 to 5.2 Could this have caused this problem? Everything else seems to work fine.

Please help!

Kind regard,

i am upgrading my drupal4.7 site to 5.1

when i make change in block module i.e.

when i am replacing module_exist() to module_exists() it shows following fatal error

Fatal error: Call to undefined function module_exists() in C:\Program Files\xampp\htdocs\drupal-4.7.7\modules\block.module on line 219

so please send me solution on this error

I replaced the files in my Drupal installation that changed in the 4.7.7 patch:

bootstrap.inc
common.inc
poll.module
profile.module
user.module
system.module
settings.php

I put the relevant info back into settings.php and ran update.php

Now I keep getting "network error" and can't login!
