Hi guys,

the first 70 users are registered and most things work as they are supposed to. Unfortunately the php_error_log is growing pretty fast as I get a lot of warnings concerning "Invalid Multibyte Sequence". 

Here is a snippet from the error log:

Does anybody know why Mahara is producing this error?

thx Alex

That problem used to happen in older versions of Mahara, because we weren't using the multibyte string functions when shortening strings. But we fixed that in newer versions.

What version of Mahara are you using? If it's not recent, you might want to upgrade. And if it is recent, make sure you have the multibyte string extension installed for PHP (mbstring).
