FS#2807 toolbar buttons disappear in preview
When entering the editor all the toolbar buttons (also from plugins added ones) are displayed.
After pressing the preview button, the toolbar reloads, but only the main buttons are shown, the ones from plugins (I think it's like that) which include the mediamanager aren't displayed anymore.
Problems with the toolbar are usually caused by old and/or not up-to-date plugins. Please disable all plugins, check if the toolbar is fine (it should), and then add back the plugins one by one to find which one is causing the error.
Outdated plugin bug, report to plugin author or adopt plugin :)
