There are remedies in the comments for the bug.
Thanks,
Melissa.
Using Mahara 1.5.1 we have a situation where some learners are unable to access their journals form the journal tab. For example learner A has three journals but only one journal is visible on the journal page, yet if she cerates a new page and drags a journal to that page she is able to choose from her three journals.Additionally she is unable to cretae a new journal. I have checked her settings and it is nothing to do with enabling multiple journals, because that option is not available becuase she already has multiple journals.
As I said this does not affect all leaners and I cannot replicate the problem, on any of my accounts.
I look forward to hearing any ideas you all may have.
Kevin
