Hi, I posted a support ticket yesterday about the same thing on one website I just started, so I decided to see if I could install this on another website that I've used for several years, and it also failed with the same results.
Is it because I'm just a trial member? If I joined would I have access to this plugin?
In the other ticket I posted, someone kindly sent me a link to the plugin and I attempted to upload it through the regular plugin interface. I did that with this new website. and it seemed to work, except it told me I needed to upgrade to coursepress2. BUT suggested I backup before I do that, so I followed those links and installed snapshot... which... ended up crashing my system.
So, I'm not sure if my hosting can't handle your plugins or what. BUT it seems to work a littl ebetter when I don't use the WPMUDEV dashboard, but I can't seem to find where to download the plugins. Is that ONLY available after my trial?
