I know of the following and most are being fixed by develper in next update. I'm also implementing some coding updates develper shares as intermediate fixes.
1. Subscription/donation process does not work 2. Formatting issues with navigation links at top and few other places. 3. Cookie crumb links don't show main category. 4. Issue with permissions when turn on search engine friendly url links. See error msg as such and prevents you from logging into forum. 5. Formatting for few sections centered when need to be left aligned.
Received email someone can log in but can't post which need to look at this week.
