My for sale new topic won't post

[Rocky7]

Hi
Don't know why but I've tried to post a 'new topic' in the for sale section today but it won't complete the post.
I've only sold one item previously on here and that all worked fine, but today after I press the post button the screen just goes grey and nothing happens - I've tried it 3 times over the course of the afternoon - any ideas or help appreciated?
cheers

Hi rocky, I've had a snout through your profile and all you permissions are correct and your subscription is valid.

I'm at a bit of loss, it could be your browser cache needs clearing, that normally can lead to issues, especially if uploading or adding pics to threads

Hi Jaymz
Thanks for checking, I did attach a some photos so I'll check the cache and photo files and try again.
Cheers
