Can open other secure web sites. Small icons in FF bookmarks have disappeared but appear in Safari. Have followed all suggestions in help regarding Cookies, Cache and plug ins. Every attempt to access site results in error message as follows: "Error 500--Internal Server Error

From RFC 2068 Hypertext transfer protocol -- HTTP/1.1: 10.5.1 500 Internal Server Error

The Server encountered an unexpected condition which prevented it from fulfilling the request."

See this about the missing icons:

It sometimes works if I open the main page and middle-click the link to open the "New Year, A New You…with a Little Help from My HealtheVet" link in a new tab (Ctrl + left-click does the same).
Sometimes a reload with bypassing the cache is needed ("Cmd + Shift + R" on Mac) to make it work.
So there is something wrong with that server.
