Then I created blank wiki page where I pasted the code and strip some parts of the code away. First I strip the code for Public spaces listing away and then page worked well. For one of my colleague I stripped the code for My memberships away and listings worked but without My memberships part, of course. For someone some of the code will work but the same workaround does not work for everyone?!
I found that code parts for listings Public spaces and My memberships produce errors. Yesterday when some more spaces were created (16 registered users) and All my spaces suddenly started to work. I hope this will help you to catch the bug. If someone found stable workaround for this I will adopt it right away. -Jarmo > >> Where I can find XWS.MySpaces?
