Re: Allowed memory size?
Since you had single-user WordPress installed before, I’d suggest doing a clean install. This means making sure that you delete both the single-user WP and the newly installed WPMU files. Also, delete your MySQL database and start with a new one.
I assume that you do not have any data yet. If that is correct, then you can safely proceed down this road. If you do have important data in the MySQL DB, then you should back it up first.
Also, you should use a separate MySQL DB for WPMU. Do not use the one that you are already using for single-user WP.
Follow these instructions for help on installing WPMU. Make sure you read through all instructions linked below before beginning the install:
- Download BuddyPress from here
- Read the readme.txt file that comes with the WPMU download
Then, once WPMU is installed and functioning properly, follow these instructions for help on installing BuddyPress.
- Read the readme.txt file that comes with the BuddyPress download
