Thank you kindly. It was complaining about the differences in time zones in the system and php.ini.

Just installed Kamailio onto CentOS 6 using the available YUM repos., and Siremis (v4.4). I seem to be having the same issue as this was reported https://github.com/asipto/siremis/issues/3 I have retried the Siremis install again as suggested, and I still cannot login with the same results that person has: click login and nothing is occurring, except for the text appearing which states "Processing Login." There is no error in the httpd error_log file. Anything else to look for? Thanks!
