He is his own hosting provider 🙁
Memory error is Window$’s fault, not Apache, not PHP, not MySQL.You can try other versions of Apache, PHP and MySQL.
It seems like you didn’t set the default index in IIS.
Try to set default index file to default.htm, default.asp, index.php
I have the same errors like Aeros.
The situation seems like:
(1) When I log in at http://www.mydomain.com/wpmu/main/wp-admin/login.php , it sends my request to http://www.mydomain.com/wpmu/wp-inst/wp-admin/login.php, thus the variable “main” disappeard, the “main” didn’t send to the login process.
(2)Because the “main” didn’t send to the login script, you can see in Aeros’s error message: WordPress is looking data in table “wp_wp-inst_options ” instead of table “wp_main_options” .
So I think the problem might be in .htaccess or login script, because there do exist tables named “wp_main_FOOBAR” tables in my database, and I think WPMU should reading data from these tables.
