Service Temp Unavailable Error Message

[axman]

I've been using SMF for sometime.  It is a great product. 

I have it linked on my website frontpage www.170220.com  as Forum, opening in a separate window.     

Recently, several members have been getting "service temp unavailable" error messages.  There is no problem with the server mysql.   I upgraded to the 1.1. beta 4 version.   I have the permissions set for guest to view text and attachments, but must be registered to post.   Upon getting the message 1st entry, if I close the forum window, and then open it again, it will go into the index file as a guest.
Interesting, Mozilla browser does not present this downtime error msg, but IE does consistently.

The link off the frontpage is set as - >>>   hxxp:www.170220.com/Forum/index.php [nonactive]
I tried using the ?   after php but does not matter.
Is this the correct link (index.php) to fire up the forum software?

My website club frontpage is an index.shtml to allow SSI to a database counter program.  Most of the pages are database driven and shtml as well.    Is it possible that the shtml page format is conflicting causing this error when I open the forum?   

Would there be a better way to fire up the forum software and link it off the frontpage?

Thanks for any help you have.

Sorry for the late response.

Sounds like an Apache error message.  Does it only happen with the forum, or both the forum and the static content?  Never Mozilla?  Any timeframe it's more likely during?

Yes, index.php is correct .  Using shtml (SSI) should not cause any problems with the server - generally, it's pretty efficient.

I know you said it's not MySQL, but would you be willing to upload the attached status.php file to the Forum directory, and post a link?  It'll help me see what's going on on your server.
