There must be a bug. I installed 1.6.3-dev from github and some plugins.
Many fields of the plugins could be found afterwards with "content" → "1048576".
I checked also an 1.6.2 installation where I am enabled categories, there I found in qa_options:
title |
content |
xml_sitemap_show_categories |
1048576 |
xml_sitemap_show_category_qs |
1048576 |
That's why I conclude there must be bug in the "initialize database" dialogue at least.
PS: Btw, initialize database got frozen after I pressed it for some plugins.
