Drupal 7.14, DS 7.20, php5.3.20. I have a site with 8 content types, which using DS, in display mode, use 180 added DS block fields. I get an Ajax 200 error when I try to modify the fields on the page. I AM able to move them within regions (but then changes will not save), I cannot move a field to another region, add a new field, or even change display mode from DS 2-col stacked back to "none".
The error evidently derives from line 312 in ajax.inc when calling $form_build_id = $_POST['form_build_id'];
What makes this interesting is that I have installed the identical drupal core and modules on my dev server (a laptop) and another host (iPage - php5.3.13) where I AM able to make those changes - it works. Thus, it is probably NOT the module(s), or the code, but how long it takes to do the callback, or something at the host - (database access maybe?). Memory at hosts is 256MB (I am told).
I seek is advice on:
1. what to tell/ask my host (Hostpapa) to get it to work on their servers;
2. How to disable ajax on my DS so that I can modify my nodes and the display on my content types; or
3. What alternatives I have to DS to use fieldgroups and views blocks in my nodes if I am unable to effectively use DS.
Thank you very much for any advice an experienced developer can provide.
