Pager encoded commas I added a pager to a site I'm working on and the URL for a page comes out to: http://example.com/blog/0%2C0%2C0%2C0%2C0%2C5 which is an encoded version of */0,0,0,0,0,5. However, I'd like the URL to be http://example.com/blog/5 or similar.

I'm using Drupal 7.31 and have clean URLs enabled.
It sounds like you have a "Pager ID" value set in your view. From your example my guess is that it's set to "6" instead of the default "0". Check within the "Pager Options" of your view display to see if this is the case, and if so, change that value to 0 to restore the URL to a more standard form.

It's important to note that there are of course some situations where your need this pager ID to be set, notably if you have multiple views, each with pagers, displayed on the same page. If this is the case, and you have to use a pager ID > 0 on one of your views, you could set it on your "secondary" view (the one users are less-likely to page through) and leave it at 0 for the "main" view.

It also looks like you have the "Clean Pagination" module installed, or something similar? Normally I think a paged URL would have the pager query string (?page=#) exposed, so you must be doing some special clean URL processing for that. Still, I think the "Pager ID" notes above would apply regardless.
