All of the sudden my site crashes and I can not even access the main page of the site.
The error message is as follows:
-----
Fatal error: main(): Failed opening required 'c:/inetpub/vietnamtown/html/class/template.php' (include_path='.;c:\php4\pear') in d:\inetpub\vietnamtown\html\header.php on line 62
-----

I tried to search the forum using "header.php" and "template.php" and have not found any post that has similar problem.

You can visit my site and see the error

Thanks in advance for your help

next time it happens, log into phpMyAdmin or the equivalent on your site and take a look at your SQL database. The error messages you receive on your blank homepage look like the ones i get when my site exceeds the max_questions resource for SQL queries.

If it is the same issue for you, the issue should be periodic, especially when you are installing modules or during heavy traffic on the site, like in chat or forums, and the site should miraculously re-appear usually within one hour.

When you log into your SQL dbase, instead of seeing the database structure, you will see an error message indicating max_questions exceeded. (that is, if it is the same issue, which it may be).
