I haven’t had to use the client in a while and have recently gotten back into DMing. When I click to roll attacks and spells, the prompt appears up in the chat, but upon clicking “attack,” no roll appears. I’m not super technically inclined so I’m having difficulty troubleshooting. Can anyone offer assistance?
Which modules do you have installed / configured?
It could be the modules installed, or the attack was made before you loaded up the game, in that case you will have to make a new attack.
If you could provide some kind of list of modules that would be great!
You can also check console (f12 → console) for any red errors, screenshot them, and we can have a look! 
I’ve tried loading and reloading the game several times; this issue’s been persisting for a week or two with no luck. I’ve also tried activating and deactivating all of the modules too and that doesn’t seem to make a difference.
Here’s the mods I have goin’:
And I’m not seeing any error messages that pop up on the console tab, but I’ll show you what I’m seeing:
and then nothing at all shows up after I’ve clicked attack in the chat box prompt.
Ah ha! I realized that it had been a while since I updated the actual game system. Updating it solved my issue and I’m all good! Much thanks!
Good to hear. Glad you got it sorted.
Have a look at these modules you might find useful:
Tidy UI
Find the Culprit
Forien’s Copy Environment
Argon Combat Hud
Combat Carousel
There are many that add useful functionality to your game.
