I have been running Pro Sites for over a year. I cannot upgrade to the 3.5 xxx version. My goal is to have Pro Sites signup on site #49. However, I cannot get the check-out page to work.
To troubleshoot, I have removed all plugins except Pro Sites and WPMUdev Update. Theme is 2014 and it is still not working.
I then changed the wp-config Pro Site definition to the main blog and still no luck.
The Check-Out page is not being generated correctly. On the Pro Sites settings page, when I tried to edit the Check-out page and then save to generate a page for the new site - it is linking to a media file.
Prior to removing all of the plugins, I had been using the Premium Plugins module and I was getting the following Errors on Feature Table page: Warning: Illegal string offset 'level' in /home/ueotest6/public_html/wp-content/plugins/pro-sites/pro-sites-files/modules/premium-plugins.php on line 493
