I'm having problems with the forum interface. The tabs at the top of the page don't pull down anymore.(see Pic). Also I'm not able to see attachments on posts. Did I push a wrong button to disable these functions?
Any help would be appreciated
Just checking semantics: When you say "pull down" you do not mean swiping on a touchscreen, ccorrect? They are either clickable links (if no arrow) or drop down lists when you hover (this is a Windows 10 PC.)
Couple of suggestions even before restarting as
suggested -- try another browser (Chrome, Firefox, Edge) Even if this solves it, a restart is usually advisable. If you don't have another browser installed, try a private/incognito window.
If that works, if you are using Firefox or Chrome, check if an update is pending.
Restarting usually cures these glitches. I would suggest a shutdown, followed by a power up (cold boot) rather than restart (warm boot.)
Not that this should apply here, but a totally cold boot involves powering off PC, pulling the plug and holding down the start button for 10 seconds to clear virtually all caches. On a laptop, you have to pull the battery out as well as unplugging the AC adapter.
