Ok i found the culprit & it was not CalPress!
The problem was the mix of BuddyPress+WordPress on MAMP.
Step 1: Increase PHP.ini Memory Limit
To start, you must increase the amount of memory available to php by editing MAMP’s php.ini file. This file is located inside your MAMP application folder.
If you are using PHP version 5.3.6:
If you are using PHP version 5.2.17:
Next, search for the line “memory_limit”. The default value is 32M. I have chosen to increase mine to 256M, as you can see below.
Step 2: Edit .htaccess File
Next, we must add a single line to our .htaccess file in order to allow our WordPress installation to utilize the extra memory we just allocated to PHP. Your .htaccess file should be located in the root of your WP installation (ex. /www).
Note: This is a hidden file. In order to view this file, you must make hidden files viewable. If you’re on a Mac, I recommend using the ShowHiddenFiles application.
If you have your hidden files set to show, and you still do not see the .htaccess file, try enabling Pretty Permalinks from within your WP Dashboard.
Once you have found the .htaccess file, open it in a text editor and add the following line:
php_value memory_limit 256M
Step 3: Install BuddyPress
That’s it! From this point, you are now ready to install BuddyPress. You should be able to activate and install the plugin as normal.
I hope that this helps some of you that have struggled with using BuddyPress on a local installation like I have.
