I’m the s2Member lead dev. I did some research on this issue and posted a follow-up here in our own issue tracker. We are making some progress, but it seems there could be some changes necessary in bbPress also. I’d love it if a bbPress dev could take a look at my report here. Thanks! Please see: https://github.com/websharks/s2member/issues/321#issuecomment-54722088
I’m lead lead dev for s2Member. I’m not aware of a specific problem at this time. However, I am opening an issue here so that we can investigate this also. I will update once we know more 🙂 See: https://github.com/websharks/s2member/issues/321
Please feel free to post any additional details (e.g. ways to reproduce the issue) at GitHub, should you find any further evidence of this being the fault of s2Member.
