I'm still using 1.4 for the moment, so it may be this problem is one no one will want to answer. But here goes anyhow!
I have successfully used Wikis on sevral occasions, but today something odd happened.
Firstly, I gave a Wiki the title 'Q - Input/Output devices' where Q represented the word 'question'. When I saved the Wiki and went to edit mode it said 'Q - Input' ONLY as the title!
Secondly I tried "Q - Input & Output devices' and it did the same.
Thirdly, when I typed in my first text it would not allow me to put [ or ] around numbers as I needed to - they did not appear, instead a '?' appeared in plase of them.
Fourthly, when I completed my first entry, and wanted to retrun to edit it - to remonve the [ and ] which did not look right, there was no text to edit, the box was empty.
Can anyone explain what might have been going on?
