Installing on localhost. After succesful install blank white screen

not techy designer here trying to setup my modx site on localhost. I've done this all successfully numerous times for other site. But this time it just wont work (is there something different in the latest release - Nov 2011)

I've setup my database through myPHPadmin connected successfully and follow all the steps to the end. Then i enter my username and password - blank white screen!

does anyone know what going on?

Mamp Pro
PHP 5
Modx 2.1.3

Try clearing your browser cache and cookies.

Indeed; if you've been working with other local installations an old cookie hanging around from an earlier installation to the same domain (localhost) would cause the problem.

I just updated a localhost site and couldn't get past the login screen. Clearing the MODX cache and the browser cache didn't help, but clearing the cookies did.

try clearing cache and cookies. I even tried in another browser but it's the same everywhere blank?

I've tried an older version of modx 1.x and it all works perfectly. So something is leading me to think that it's something to do with the latest version.

My database has been loaded with of modx content modx_* etc

I can get the log-in screen http://localhost:8888/labplum/manager/
after log in
BLANK!

anyone any ideas. i've been searching the forums but everyone seems to have variants on the blank screen but for different reasons.

(incidentally, i installed joomla before on this mamp aswell with no issues)

There are some other ideas here: http://bobsguides.com/modx-installation-faq.html

Most of us use XAMPP, so it may be some interaction between MAMP and the new version as you suggest. Make sure mod_rewrite is enabled.

One other possibility is that one or more files somehow got corrupted, although this isn't usually a problem with localhost installs unless you used FTP for some reason.

ahh... so I finally managed to get something going and it will work as a temporary bodge for now...

I have Mamp free version and Mamp Pro. (I purchased Mamp Pro expecting it to replace the normal version but it they both seem to share the same folders... bizare?) I think this may be the problem.

I noticed that the PHPmyadmin launched via Mamp pro wasn't showing my edits to the php.ini. (I changed the memory from 8M to 64m.)

so my fix is to use mamp free - create a database there and connect with modx. All works fine now....phew.

It's all still up in the air but at least it's working.
