You have got a huge heap of plugins running. The first rule of troubleshooting is to reduce down to the most basic functionality to produce a test case that demonstrates the issue or not, ideally one runs the basic installation which will not demonstrate the issue, then start to add back in plugins one by one checking each time to see if the issue kicks in again, or work that in reverse and start disabling plugins one by one checking as you go so that you know what plugin causes the problem.

This is exactly the same reason we ask that people drop back to the default theme as doing that tells us immediately if an issue is related to BP or a custom theme.
