[Solved] It is not possible to edit posts
Please make sure the Wordpress Rich editor is enabled for you in Dashboard > Users > Your Profile admin page. Also Please deactivate other plugins and test it again. Some plugins affect wpForo rich editor, examples:
I can't edit posts, even though I'm admin, just is download and all.
As for Dashboard > Users > Your Profile admin page, everything is fine. Turned off all plugins did not help.
But can it all influence bootstrap?
You have JS error on your website, it affects wpForo editor.
Use Firebug or Chrome console to see JS errors.
