How compatible is Indexu 3.2 with PHP 5 or the latest version of MySQL. All my Indexu directory stop working all at once, it look like the Mod_rewrite is not working, it can not create new file in the cache directory or serve the ones which are there. In the same server Indexu 5.1.1 is working fine so I now that mod_rewrite is unable.
BTW I am unble to access admin
An other piece of information: The script can still create (in/cache/ index_.html, new_.html, etc but it would not create browse or detail pages. The script would not serve them (detail and browser) even if they exist in cache folder.
Here the content of my .htaccess

AddHandler application/x-httpd-php .htm .html
RewriteEngine On

RewriteRule ^browse-(.*)-(.*)-(.*).html browse.php?cat=$2&pg_which=$3
RewriteRule ^detail-(.*)-(.*).html detail.php?id=$2
RewriteRule ^new-(.*)-(.*).html new.php?st=date&dt=$2
RewriteRule ^new-(.*)-(.*)-(.*).html new.php?st=cat&id=$2&dt=$3
#RewriteRule ^new-(.*)-(.*).html new.php?st=cat&id=$1&dt=$2
#RewriteRule ^new-(.*).html new.php?st=date&dt=$1

My sites have been down for almost 4 days. HELP!!!!

Help Suggestion are welcome
