This is an overall problem which is happening on all the Forumotion forums, all over. It is NOT a fault with the forum itself, but is dependant on which browser you are using.
If you are currently unable to see these buttons (as portrayed in this post), then it means that you are using one of the affected browsers (i.e. CHROME or MS EDGE - and maybe some others).
The immediate solution is to change your browser to FIREFOX - which is working absolutely fine and you will be able to see all the missing buttons.
My personal recommendation would be to use FIREFOX as your default browser anyway (which I do, as my personal preference), as problems like this seem to happen quite regularly with some other browsers, and FIREFOX users don't experience any problem at all. In fact, I would not even know there was a problem at all, except that a load of forum owners have reported this issue on the Support Forum. Seems it has been an issue for a few days running.
