YouTube upload problem

I've been uploading a bunch of 1080p clips to Youtube and I've started getting failed uploads and receiving this message:

Publishing to YouTube Failed: The operation couldn’t be completed. (The request metadata specifies an invalid video title.)

I have no idea how to fix this. I've remade the title (on the Share page) - eliminating quotation marks, question marks - anything that might cause trouble. I've tried copying the project and trying a new title altogether and it still won't upload. So far, my other clips are uploading fine. Any thoughts? thx

Maybe something corrupt in the particular project like a bad render file possibly. You might try deleting all render files in the events and project, or even in the entire library and try your upload again. Also, see how far the share progress wheel gets before the error appears. Does it get to 50 or 60 percent consistently when it fails or does it never progress off zero? This might point you to a place in the project that is the culprit such as a clip with a bad plugin or render file.

Yeah - that's what I finally did. It wasn't a very involved clip so I just reedited it and it worked out. Whatever screwed it up disappeared. Thanks.

DG has the right idea. Delete all render files, do NOT re-render, just export, see what happens. Then see if it fails at the same location constantly. Yeah, try the simple and cheap first, then work our way up.

Hadn't thought of deleting render files. I'll do that if it happens again. It would save some time. Thanks.
