I did some troubleshooting on my site and narrowed the problem down a bit.
First, my apologies to you, alanft. There is no incompatibility with WP 3.7.1. My judgment of that was rash and assumed that all of my plugins are compatible. If I use WP 3.7.1 and only activate WL, everything is fine.
I narrowed down the incompatibility of WL to two plugins — Hybrid Tabs and BP Group Documents. Hybrid Tabs is currently unsupported and has been replaced with Whistles. I haven’t checked compatibility yet, but I also don’t rely on Hybrid Tabs, so I’ll ignore that incompatibility.
However, the incompatibility with BP Group Documents is real and a problem for me. I rely on that plugin for my users to share documents within the subscription portion of our site. The symptom is the one I said at the beginning — I get a blank white page because the entire output is just an empty html page.
I don’t know which plugin is the “most culpable” for the incompatibility. As I have my site tuned to for using WL, I would prefer to just keep it. However, if it can’t be made to play nice with BP Group Documents, then I will need to use something more heavy-weight to regulate my widgets.
Please let me know if there is a simple solution forthcoming or any recommendation for how to resolve the issue on my end
Thanks.
