Hello,
I’ve activated CMB2 plugin. https://www.8theme.com/documentation/xstore/plugins/included-plugins/ Please check [8theme] Layout options now – http://prntscr.com/l9x5h0
I’ve deactivated Massive Addons for Visual Composer plugin, so you can edit pages now. There is a known issue of the Massive Addons plugin that caused by server limits https://codecanyon.net/item/massive-addons-for-visual-composer/14429839/comments?page=36&filter=all#comment_14143143 https://codecanyon.net/item/massive-addons-for-visual-composer/14429839/comments?filter=all&page=79#comment_18501820 Please contact your hosting provider and ask to increase the maximum body length value, then enable the Massive Addons plugin and check if pages can be edited.
