Re: New Install, Several Mysterious Issues (usability)
I had the problem of “no submit button” on status message with the latest BP – it was due to some other plugin using some sort of jquery. I had to disable one by one and get back the “submit button”. Thus apparently it was not fault of the latest BP. You have mentioned you have turned off all BUT sometimes, I have seen, js files remaining in browser /server cache/memory whatever.
What happens (for member pages) if it is ordered by alphabetical ?
Stubborn files not getting deleted may be deleted by FTP or Control Panel/Admin Panel of your webhost but this may also break things so backup!
A good idea will be test things on locathost with WAMP or similar, with latest stable BP and WP and see whether things are working for you. If they do work, it will mean cleaning/changing files manually and/or db tables will get the things back in shape.
I am not a pro, in fact really have no expertise but these are somethings I do myself when stuck.
