I just put SLP 3.7.7 up on the CSA website for the Pro Pack users, however I have not tested this patch yet. Proceed with caution.
For users with the Pro Pack...
Go to http://www.charlestonsw.com and login to your account.
You should be able to get to your account info where it will show "downloads" at the top of the page.
Download the store-locator-le.zip file (should have today's date with a timestamp of 23:XX EST).
Check that the readme.txt says version 3.7 near the top.
You can then go to your site, deactivate SLP (probably already have), delete it (probably did that too) and then go to Plugins / Add New and upload the new .zip file.
Please make sure you have FTP or command line access so you can remove the plugin directory if this patch fails.
If it works please let us know so I can push the formal SLP 3.7.7 release through the WordPress plugin directory.
Grrrr... this is not the first time PHP version differences has bitten me in the butt. Unfortunately NONE of the modern web development platforms I use come with anything but PHP 5.3 or higher (some even PHP 5.4) now so setting up a PHP 5.2 development system is a big chore.
