Unable to take screenshots

(SOLVED)

Hi,

I noticed that when I try to take a screenshot, I see the message in-game that a screenshot was captured, but no image appears in the Screenshots folder. Previously, I had some folders of old screenshots in said Screenshots folder, and I decided to move those to another archive. I also recently installed some AddOns, like Addon Control Panel, PlateBuffs and DrDamage.

I tried to delete the Screenshots folder and to take another screenshot and what happens is that when I take a screenshot the Screenshots folder gets created anew, but no screenshots is saved.

Does anyone know what's going on?

EDIT: I managed to solve the issue by creating a new WoW folder by hand. I moved all the files inside the new folder and I was able to take screenshots again. Now the system is saving them properly.
I don't really know what it got solved by creating a new folder though. As I said in the comments, it stopped working all of a sudden. The only recent changes I applied to my old WoW folder were a few addons and the fact that I moved old screenshots from the default location to another archive, in order to keep things clean and tidy, but removing these changes didn't solve anything. I tried to remove all the addons, I tried to delete the cache and the old screenshots folder, nothing worked. I deleted my old WoW folder, hoping that this issue won't show up again.

Open WoW folder's properties, then un-check read-only.

Hey, thanks for the reply. I tried to uncheck the read-only property, the it always reverts to read-only. I looked for some solutions online, but nothing seems to work.
The thing is that it was working just fine and then it suddenly stopped saving screenshots. I never had issues with read-only properties.

Hello again, I solved the issue, so I'm gonna edit my post, explaining how I managed to do it.
