I am having the same issue here. The activities table in "View Contact" has no any records show. And the other issue is the "activity report" throws me a "Fatal error: Call to undefined function cal_days_in_month() in /usr/local/apache2/htdocs/mysite/sites/all/modules/civicrm/CRM/Utils/Date.php on line 1056"

More information:The illegal character error occurs on loading the contact view page and before accessing the Activities tab. According to Firefox, the page is utf-8 but the js file is ISO-8859-1. A second error occurs when trying to view the Activities tab:cj("contact-activity-selector-" + context).dataTable is not a function. This same error was reported and fixed for dashlets in another thread on the forum but that post doesn't contain any details of the fix. http://forum.civicrm.org/index.php?topic=19538.0As a test, I set the character set of js files in my .htaccess file:Firefox reports the file is utf-8 but the error still persists. I have attached a screen shot of the first couple of lines of the file with the encoding shown in Firefox. I have deleted the c_tempates directory and cleared the cache with no change.
Have you tried doing a Google search on that error message, and also searching the forum for the dataTable plugin?
