Post installation

Greetings. I'm wondering if anyone has any insight into this dillema.

I have my "Discard access logs older than:" set to 16 weeks, but they are discarding after 4 days. Below are my settings from the 'variable' table in my database that pertain to site statistics, as well as the source code from the "/admin/settings/statistics" page where the variable is set. Both the database record and the HTML source both show 9676800 for the "statistics_flush_accesslog_timer" value, I'm unsure what type of measurement this is, and if it's correct, maybe someone out there knows?

Much appreciated.

"Variable" dupal database table setting pertaining to site statistics:

statistics_day_timestamp  	i:1150860773;
statistics_enable_access_log 	s:1:"1";
statistics_flush_accesslog_timer 	s:7:"9676800";
statistics_count_content_views 	s:1:"1";
statistics_display_counter 	s:1:"0";
statistics_block_top_day_num 	s:1:"5";
statistics_block_top_all_num 	s:1:"0";
statistics_block_top_last_num 	s:1:"0";

HTML source from "/admin/settings/statistics" showing "Discard access logs older than:" choices:

For the search module, what exactly does clicking the re-index button do
that running the cron job doesn't do?

(By running the cron job I mean accessing: http://www.mysite.com/cron.php )

When (if ever) should I click this button?

Ive been running 4.7 for months now without incident until last night. I browse to the page and it's blank. We haven't made any changes to the website for about a week now so this outage is totally unexpected. Other scripts on my host seem to be working fine as well so I'm starring at my blank drupal page scratching my head.

I don't have a recent backup. I just deleted the backups I had in the home dir and forgot to make new ones the night I did it. DOH!

I ran a repair on the database everything is cool from there and the files seem to be intact.. I dunno

I'm trying to use the Categories module for my website, but when creating a category inside a container, I get the following error.

I use this page so I can get a snapshot of recent visitors by IP (or username if they're logged in). It works when it doesn't time out but it's really slow. I only really need the last 2 days or so of visits so I thought maybe I could fetch those records first and then run the query on that, but I have no idea how. Does anyone have any suggestions for improving this? Thanks, Michelle.

Using Drupal 4.7.2

In Home » administer » settings
User registration settings
It seems to be locked on:
Visitors can create accounts but administrator approval is required.

I check the other boxes and "Save Configuration" and/or "Reset to Defaults" but it always returns to above permission.

Also can't seem to find anymore the User Permissions where I can change according to user roles access to read/write of different content types.
