Hey Mark, just thought I would let you know what I have been doing in the mean time, or for anyone else running into this temporary problem. The previous version of tbtestimonials does store the company name and website correctly, so I installed the old version, and then entered all of my testimonials, and then upgraded. the excerpt function doesn't work, but the company name and website are stored from the previous version and the new version pulls the company name and website correctly, so you can still use those features.
Also Travis, I ran into the problem that tbtestimonials (newest version) was using/calling jquery cycle, which I am already using for another feature on the site. Calling this twice caused all of my jquery to crash. I thought it might be helpful to put a checkbox in the plugin options to turn off pulling the jquery cycle. I was able to dig into the code and comment it out, but for other users this may not be a possibility. Otherwise (if its not already there) you could put a little note in the documentation.
Thanks again for the great plugin travis, I cannot wait until it is all working in full, and I plan on sending you a donation for all of your work once the plugin is working in full.
