CMS Made Simple Forums

I've had my site running for years now with CMS Made Simple with no problems at all and I visited the homepage today and received the below error messages. Does anyone know what is wrong?

string(106) "Smarty error: [in template:21 line 5]: [plugin] unknown tag - 'sitename' (core.load_plugins.php, line 123)" string(103) "Smarty error: [in template:21 line 5]: [plugin] unknown tag - 'title' (core.load_plugins.php, line 123)" string(106) "Smarty error: [in template:21 line 6]: [plugin] unknown tag - 'metadata' (core.load_plugins.php, line 123)" string(108) "Smarty error: [in template:21 line 7]: [plugin] unknown tag - 'stylesheet' (core.load_plugins.php, line 123)" string(103) "Smarty error: [in template:21 line 12]: [plugin] unknown tag - 'menu' (core.load_plugins.php, line 123)" string(106) "Smarty error: [in template:21 line 18]: [plugin] unknown tag - 'content' (core.load_plugins.php, line 123)" string(103) "Smarty error: [in template:21 line 19]: [plugin] unknown tag - 'news' (core.load_plugins.php, line 123)" string(113) "Smarty error: [in template:21 line 23]: [plugin] unknown tag - 'global_content' (core.load_plugins.php, line 123)"

We have been having the exact same smarty error problem. It is intermittent such that our homepage only works about 1% of the time. Did you find a solution? Larry_p3@hotmail.com www.EarthDayHamilton.ca

need to know a lot more about your setup if you want help.

CMSMS version, server information, PHP version, installed modules, etc...
