Cpanel comes up, looks good, but stuff missing and buttons don't work

I'm interim webmaster for a small website. The old webmaster is very busy with ...other stuff and is generally non-responsive, the owner (totally non-technical) is looking for a new webmaster, and in the meantime, I'm trying to do some maintenance.

I have log-in privileges sufficient to enter cPanel. It's cPanel Version 11.30.6 (build 3). At first glance cPanel seems to be functioning normally. Stats look reasonable. I can navigate to various sub-pages.

I need to add a FTP account. When I navigate to the FTP Accounts page, it looks reasonable. I see three subheads:

Add FTP Account

FTP Accounts

Special FTP Accounts

Immediately I know something is wrong, because no accounts are listed, and I _know_ several FTP accounts exist. Further, if I try to add a new FTP account, text entry works, but none of the buttons work. For example, I can click on "Password Generator" all day, the simple "press animation" occurs, but nothing happens.

Maybe a browser problem, right? I tried multiple browsers on a fully-up-to-date Mac, another up-to-date browser on an old WinXP box; no better results. I also tried emptying the browser cache on each. Finally, I borrowed a brand-new Android and found that I could see some existing FTP accounts. I managed to establish the new one I wanted. No problems at all, except of course the difficulty of working on a small screen with an on-screen keyboard.

Any ideas about the cause? The cure? Is there anything I as a user can do to make this work on Firefox/Safari/Chrome/Opera on my Mac? What could I try?

I would ordinarily contact the hosting service and ask them for help, except I haven't got full credentials -- and don't want them, 'cause I'm just filling in, don't want the job.

TIA

 

Right, thanks to both of you for your replies.

Ordinarily, I would give up at this point. The official new webmaster can take care of it -- and will be paid to do it.

But I'm a bit obsessed by the fact that the brand-new Android accessed the same cPanel installation perfectly well.

So I went back to Firefox on my Mac and tried it again, with the error console activated. Now cPanel is functioning perfectly .

Hooray! The only explanation I have is that a Firefox update arrived yesterday. Maybe this cPanel installation is using some component (say, Javascript) that's really new and needs the clients to be up-to-date to match.

Case closed! Thanks for your help.
