Warnings on Configuration of Fieldgroup

Nope: I guess this is a problem with the development version of CCK, not the fieldgroup tabs modules. After disabling the fieldgroup tabs modules, I still have the same problem.

Okay (sorry about the rather general report): I have created a custom content type with 10 field groups and 74 fields, including the title. Most of these fields are text areas with a row set to 10, but I also have some smaller text fields included (nothing too fancy). My input filters are set to user input. I installed the fieldgroups tab module after creating the content type, most of the fields and all of the field groups. The error occurs when selecting "configure" for the field group from the "manage fields" screen. The next screen after clicking the "configure" fieldgroup button gives me only the warnings and the title "Edit Group." No options are available, only the warning. I am using the latest development version of CCK, dated June 20th. I did try going back to the beta version, but received the same warnings when using that version. I am running this with XAMPP on a Windows Vista machine (I'm not sure that would affect anything). Let me know if you have any other questions that can help with this issue. It may be a configuration issue on my side, but my Drupal setup is pretty simple. The only additional modules I have installed: content template, IMCE, IMCE image, TinyMCE, Field group tabs, and Tabs. Everything else is core or in the core of CCK.

Changing status, as more information has now been provided.

After disabling and uninstalling tabs and fieldgroup tabs, the problem remains. I can no longer edit fieldgroups :(

I disabled everything except the suite of CCK modules that come with the content construction kit. Everything else comes standard (as part of Drupal 6's core). I think installing the fieldgroup tabs and tabs modules triggered these problems, as I was able to edit and configure fieldgroups before I tried those modules (they are both now completely removed from my installation). Strange stuff. I also had TinyMCE. IMCE, and IMCE image field installed. They were disabled and the problem persists.

Changing to critical, as this essentially prevents me from editing fieldgroups, whether I uninstall fieldgroup tabs or not.

Ah, and I should add that I have upgraded to CCK's release candidate for Drupal 6 and the problem persists. Thanks for any help on this.

I tested the above patch (#17), and it applied cleanly, However, I am now getting warning messages on every page of my site:

* warning: include_once(./sites/all/modules/cck_fieldgroup_tabs/cck_fieldgroup_tabs.module) [function.include-once]: failed to open stream: Permission denied in C:\xampp\htdocs\mysite\includes\bootstrap.inc on line 558.

And when I select "Edit group" from the manage fields screen, I get more of the same:

Updated to latest development version of Fieldgroup Tabs in CVS and updated to Drupal 6.3-dev and CCK 6.x dev. I get the following errors when editing a fieldgroup (this may have to do somewhat with the development version of Drupal itself, but there is supposed to be a fix in 6.3 that irons things out for CCK):

* notice: Undefined variable: node in C:\xampp\htdocs\mysite\sites\all\themes\pixture\page.tpl.php on line 63.

Using a clean install of Drupal 6.3-dev and CCK release candidate 3, I am happy to report that fieldgroup tabs 6.x-dev seems to be working rather well! I am still getting a few little notices, due to Drupal 6.3-dev's sensitive notice reporting, but nothing major:

* notice: Undefined index: #contexts_selector in C:\xampp\htdocs\drupal\sites\all\modules\cck_fieldgroup_tabs\cck_fieldgroup_tabs.module on line 103.

I get these notices for a number of other things, in addition to the fieldgroup tabs module (apparently a development level of reporting).
