block_admin_display_form_submit not getting called I am having trouble saving my block regions(admin/structure/blocks). 

Problem:
I am doing my thing on block admin page, saving blocks, moving them around and what not. but the changes i make are not being saved.

What i found: after some debugging efforts, i figure out that the function *block_admin_display_form_submit* is not called when the block form submits.

the site i am having problem is on a lamp server somewhere. i have another copy of this site on my local machine, which has no problem saving block regions.

any idea on how to fix this? thank you.
I'm having the same issue, I cannot call function block_admin_display_form_submit($form, &amp;$form_state).

I've set a custom variable that should be updated if I change block region.

Everything works if I do it from the block edit page(admin/structure/block/manage/menu_block/ID/configure), but if I try to do it in the block admin display form (admin/structure/block), It will not work.

I've tried to increase max_input_vars with no success.

Have you solved it?
