Can't configure GA without running update.php

From what version are you upgrading?
Have you run through /update.php?
Could you try to disable and re-enable the module? I haven't seen this while testing, but it sounds like a menu caching issue.

You MUST run the drupal upgrade process and I'm pretty sure you haven't done this (reproduced with upgrade from 1.3 to 1.5).

I will do another test with 1.4. As I know the update.php flushes the menu cache... but I'm not 100% sure and if this won't happen I shouldn't be able to verify that it works after running update.php and not before!?

FYI, I had the same problem after upgrading and using update.php
I watched the progress bar during the update as well as saw no error messages during the update. It did reflect the successful updates that it applied.

I'm using:
W2k3 Sp2
IIS6
PHP 5.2.6
Drupal 5.7
MySQL 5.0.51a
Updated GA 1.4 to 1.5

Thanks for all the tips to get this going again.

Removed code. update.php clear the caches on D6 and D5... i wonder what could be wrong here.

I'm still not able to reproduce this. I'm using PHP 5.2.6, MySQL 5.0.51b, WinXP, IIS 5.1, Drupal 5.7.

0. Uninstalled 1.5
1. Installed 1.3 or 1.4
2. Configured UA-1234-5
2a. Put site in maintaince
3. Deleted google_anaytics folder
4. Extracted 1.5
5. Clicked on admin/settings/googleanalytics -> Fails -> Expected behavior
6. Called update.php, run all updates
7. Go to Administration section and admin/settings/googleanalytics
8. All ok.

If you are able to reproduce this, we could try to add a fix if there is a bug.

What caching settings do you have?

Caching enabled/disabled?
Time to cache?
Webserver?
Drupal version?

Are you able to debug this issue?

I also had this problem and solved it by disabling and enabling the module.

When disabling, it gave me this error

warning: rmdir(files/googleanalytics) [function.rmdir]: No such file or directory in /_drupal_base_path_/sites/all/modules/google_analytics/googleanalytics.install on line 44.

@thoughts: Is your error_reporting set to E_ALL & ~E_NOTICE? See http://drupal.org/requirements.

Could someone try to add this to the end of googleanalytics.install v1.5 and try a upgrade from 1.4 or 1.3 to see if this fixes the problem? Please make sure you can reproduce the menu caching issue every time without the following code.

function googleanalytics_update_6003() {
  $ret = array();
  cache_clear_all();
  menu_rebuild();
  return $ret;
}

@dshaw: see #14

If you see this "warning" (not an error) you do not have ~E_NOTICE configured or you have removed this from core code. D5 and D6 is not EALL save and this is only a minor EALL issue that could be fixed very easily.

Please focus on the menu caching issue.

Added code from #15 that hopefully fixes this issue.
