@yakiv agreed, my thinking is that the friend link is only there as long as you use that invite link to register. 

Hello Cash,

To repeat the error, click sequentially:

1. Tools -> Blogs (Your blog)
2. Friends' blogs
3. All site blogs
4. Write a blog post

The error appears in the 3rd and 4th steps.

@Uddhava dasa, I just tested what you said and I do not confirm the error.

I tested it with a couple different browsers too; no problem.

Oh well, i guess then its just a problem with the extra plugins i use, or the database upgrade. I'll test on a clean setup and report.

If it is an upgrade problem, Cash and Brett still need to know about it.  Maybe you can share more about the current set-up you have and how your upgrade went.

Oh yes, just confirmed. And its not in the default install. Some problem when upgrading my installation or plugins. By the way, running very fast and smooth in a clean install.

I told Brett it runs incredibly fast and he said he thought maybe my server, but I had both setup exactly on same server and I can say 1.7 is way faster!!

Yes, that's my experience also. It must be some bug in the engine. Its about 30 or 40% faster on my site.

By the way, anyone knows how to find which plugin is the culprit when getting Form _ts errors?

Though it wasn't a goal, I'm glad things seem faster for everyone in this release.

@Uddhava dasa - There is currently no good way to figure out which plugin is causing this error beyond going one at a time through them and disabling them.

This raises a good point -- Before making any bug reports, please disable all 3rd party plugins.  If the buggy behavior disappears, it's likely a 3rd party plugin causing it.

@yakiv yeah the fly away kinda got me too at first, but i do love how they actually made it so that when you put a widget on a page it removes it from the widget storage area, my 1.6.1 does not do that and it gets confusing to know what u are using and what your not.. i like the way they did that, much cleaner look, if the fly away is the lesser of two evils ill take the fly away every day.

@brett speaking of plugins, do you think its a good idea to add a new subfolder in the plugins area for those plugins that are 1.7 ready, would make it easier to find what you need and keep track of who has updated and who has not regarding 3rd party items.
