Found the source of the problem. My hosting account has several sites on it. For vrious technical reasons the PHP release has remained at 5.4. For whatever reasons the PHP release was changed to 5.6 and problems were noticed on my other sites. I changed ti back to 5.4. The rest of my sites are working fine now but the spinner problem has come up on Visualizer. I have confirmed that it works fine on PHP 5.6 today. BUT, i have to keep the account at 5.4 for the other sites for now. Visualizer worked fine at 5.4 but does not now. I upgraded it to 3.3 when the problem seemed to start but even moving it back to 3.2 does not resolve t he spinner problem.
The following messages show up in the debug log:
