Your file couldn't be accessed message when publishing blog

Every single time I try to publish my blog post, the message appears "Your file couldn't be accessed. It may have been removed, or deleted." I never deleted my blog post, however.

I can't even save it, because the same thing happens when I press "Save and Preview"

I'm really upset because this took me over an hour and a half to make. I'm not sure why this is happening, but I hope it will be fixed soon.

(I guess I'm fine, I'll copy and paste the text into a text editor and write the moves of all the diagrams I put. I'm glad it wasn't a long blog post!)

Thank you!

I have a blog with many pages as well, but never seen this error. There might be an issue with the name of the file. I've seen in other places all sorts of weird errors when the name of the file contained special characters. Try to rename the file to something simple and try again.

Also, what type of file is it?

And where do you keep it on your pc?

And btw, all my blog pages were made on my pc, i never wrote anything directly online ( maybe just some small word adjustments and formatting), just to avoid problems. Might help to continue editing offline

I'm not sure that I've had a file for the blog. I simply wrote it on the chess.com blog area.

Can you post just a simple blog, with no header image or anything? If so, it could be that the header image you are trying to use has a problem.

That may just be it! I made the blog and it posted this time, (thankfully) using a different thumbnail image. 

oh, great
