Post installation

Greetings,

I have installed Drupal 4.7.2 and after I post a comment to a forum thread the following message appears:

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 '' at line 1 query: SELECT u.mail, u.name FROM users u LEFT JOIN users_roles ur on u.uid = ur.uid WHERE in /home/user/public_html/includes/database.mysql.inc on line 120.

This happens when user uses email notification (about new comments posted).

Can someone tell me how to handle this?

So i decided it would be best to have a local test site for testing new modules instead of doing everything live.

So i backed up my database and files and installed them in XAMPP. Everything fires up and i get my frontpage but everytime i try to access a link from there i get

Object not found!

The requested URL was not found on this server. If you entered the URL manually please check your spelling and try again.

Hi,

i am creating a website and i would like to publish it also in english...right now the site is just in german.
I installed the i18n module as described in the install.txt and everything seemed to work...

Now i tried to translate the german site to english with the translate tab...i could generate the site, but the language only changes for the active page. I also changed other pages, but these are still in german when i open them in the english mode.
i although cant change the german menu into english...

Did i forget something to activate?

After enabling comments on a blog post and adding one, displaying the full post does not work. The html page only countains a couple tags with the last comment. For example, it gives pages like this:

From time to time my server chokes and gives out a fancy drupal error message. However, I would like to change this to my own theme (at least the drupal logo) and message, or test to see if the backup servers are running and give the option to redirect.

Is there a module or theme page to change this?

example Drupal output:

Does anyone know why the number of guests online goes down significantly after upgrading to 4.7?
I've heard this happen to several people but have not found anything that explains why this happens. Are guests counted differently in the new version?

Before my upgrade my guests online was in the thousands now it is below 100. Any ideas? Is it now measuring actual guests? I'm assuming before that search engine spiders were included. As far as I can see the settings are the same. Thanks for any insight.
