I just changed the theme of my website https://stammer.in but after changing the theme some functions from my Dashboard are missing. I can only Acess Post, Media, Pages, Comments, Events, Profile, Tools and WPBakery Page Builder. I can't access to other functions like appearance, settings etc. Nor I can access to the visual composer to which I can access earlier. Please help.
have a look at this, cause that seems to have changed for ur user with ur modifications: https://wordpress.org/support/article/roles-and-capabilities/#:~:text=WordPress%20has%20six%20pre-defined,“%2C%20and%20“edit_users“.
would be better to tell us which theme modifications u made, otherwise it's impossible to tell why what happened!
