paths prevent use of node edit alias

First, I suggest you make a test site (if this isn't one already) so you don't mess up your live site.

Then, you can remove all of your aliases by deleting the contentents of the url_alias table. That should "reset" all aliases on your site. If you want to limit your reset to "node" aliases limit your delete statement to src like 'node%' or something like that.

You then need to figure out which of your pathauto patterns is causing the problem. A little bit of testing and trial-and-error should help in that regard. Let me know how those steps turn out.

Just changing the title...

...and changing the status.

Ok, that's good to know that your problem is solved.

I believe there is already a feature request for the mypage and mypage/edit to be created. I'm not really keen on the idea because it would drastically add to the number of paths in the url_alias table which is already seen as a bottleneck without adding much value (i.e. not many people actually see the mypage/edit page so it is not used often so it's low value).

If someone else were to make a patch that added that and which were optional then I'd probably consider it, but that's for a different issue.

Thanks!
