I've suddenly lost the ability to post books.  I can't use the tag button to tag books, or the add to book list button either, but I can do those functions elsewhere.  Is anyone else having these troubles, or is it my computer?  Thanks for any input. 

The first thing I'd do is log out and then log back in to see if that is the issue.

I just posted a book. Worked fine.

Well, dang it.  That's not what I wanted to hear.  Thomas, what browser are you using?  It's been going on for 2 days for me, since I installed an update to my internet security system.

In addition to the above problems, no search box pops up when I try to search my reminder list, wishlist, or bookshelf.  I cleared my cache, but that didn't help.  I was using IE.  Today I decided to try Firefox, and everything works fine with that, but I don't like it.

You might check to be sure you have pop-ups enabled for this site.  There are some other ideas here:

Configure your browser to work with PBS

What version of IE are you using? Downloading a more recent version also might help.

I have the most recent version, and this has only become a problem in the past few days. 

We have had several members report having malware asking them to load a bogus download of Adobe Flash.  PBS does not require Flash.
