Adobe Save for Web error

[greg_0062]

I have been experiencing this error for a while now. When trying to save for web it stops working and gives the warning "Save for web error" "Could not complete this operation. A writer permissions error has occured."
Everytme I tried the different solutions found online and they worked just fine but not this time. Everything was fine yesterday but today it just does not want to write this file. 
I have tried the following:

1) reset preferences

2) update photoshop

3) Restart photoshop

4) Restart system

5) Give photoshop a complete write access to the disk

6) Checking that file and image sizes are the same

7) Trying different formats

I am on Photoshop 25.0, please help.

I had a / (forward slash) in the name of my slice. As soon as I removed it I was able to Save.

Hi, 

I know I'm a bit late to this but I kept getting this on my new work laptop (last week) and thought if other people are still having this issue my fix might be helpful to some. 

I had an export action on my old laptop (MAC) which I moved across, you may have one already if you've been able to export previously or a colleague who has one you can upload to your machine. Running this action fixed the issue, I'm not sure how but I can now run the save for web export. 

Hope this helps anyone else!

Still having this problem in 2025 even though I did everything that was suggested. Please fix Adobe, it's getting annoying!
