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.
