Upgrading Drupal

I would like to try a marker clusterer. There appear to be a number to choose from, but it would be helpful to have some guidance as to which to try first. Four appear to be configurable directly from within Gmap's configuration page (admin/settings/gmap). I turned on "Jeff Poskanzer's Clusterer" and "Martin Pearman's ClusterMarker" but neither made any difference on my map.

Reading a bit in the forum, it looks like I might need a hundred or more markers before these marker managers trigger. Is that so?

On a page with several teaser, like the front page, clicking the teaser titles doesn't take me to the node. Instead, it just links to the current page, basically refreshing the page. I also upgraded a couple contributed modules after the upgrade because everything seems to be installed fine until I found this problem. This is just happening on 1 site of a multi-site setup. Some of the others use the same theme though.

I just ran an upgrade on my site and forgot to disable all of my custom modules.

When attempting to access admin I get this error:
Fatal error: Call to undefined function token_replace_multiple() in /home/mysite/public_html/sites/all/modules/page_title/page_title.module on line 443

When attempting to go to the home page I get this error:
Fatal error: Call to undefined function token_replace() in /home/mysite/public_html/sites/all/modules/page_title/page_title.module on line 404

Here is the error:

Fatal error: Cannot redeclare image_gd_info() (previously declared in /home/trevjs/public_html/4th-st/includes/includes/image.gd.inc:18) in /home/trevjs/public_html/4th-st/includes/image.gd.inc on line 21

I get it when visiting admin pages. I can work around it by renaming the file .bak, but this limits me in certain admin tasks. Is anybody else getting this error?

I suspect that the audio and images modules might be conflicting, but this is just a wild guess.

Hello All,

I have a website build in drupal 5.12.
It's build on honderds of core modifications and custum made modules.

Now I want to move it all to a new clean drupal, without all these modifications.
There are a few things I need to move:

Forum posts and replys
Blog posts and replys
A few other contents pages, and other types.
All user login information, just the basic.

And really importand the url path's.

I just upgraded to D6.14 from 6.13 and now I am seeing WSOD. Does 6.14 need higher php memory?
