Hokay, here is an example. I have a test blog where I went in and selected stripedplus as the theme. I right click on visit site to see. It is garbled. I go back and select another, Rubric in this case. I go back and refresh and it is OK. I click logout and this shows.

I log back in and I get the backend and change the theme. Now, for some reason on my web host I get similar problems re the pluggable.php intermittantly, but refreshing or selecting another theme and going back usually get sthe themes to work. This has happened even with the default theme. Not insurmountable, but will drive an average user crazy. Sometimes I couldn't log back in on the above example. I suspect a database access issue with the web host. I get a slow one on occasion.
But in the meantime I have a user getting all bumfuzzled and confused and if they do get back in they may do something worse. Maybe not the problem with WPMU primarily, but just a collection of things. A nice little reset to square one listed in the user guide would make things much easier.
BTW, I had to go in and reset the theme to default before I could get back to normal.
I tried all of Farm's themes and they look beautiful and work and no problem, except for Stripedplus, even with the global themes plugin, other than the occasional glitch I mentioned. But it can escalate into a problem where I have a user that has to email me and I have to spend time fixing it, which will span a period of time. They do a reset and they can get back in within moments and I don't get bothered, unless they email me about the problem and then I will work to get it resolved.
I surely do not intend to give my users FTP access. I do not intend for my users to have to be computer geeks to blog.
So what is the big deal for asking if there was a plugin or hack to allow them to type a simple URL and enter a password that will reset there themes and/or widgets and/or plugins?
