Hello,

I just noticed that the export function of our Mahara installation is not working properly :( I tried exporting single views as well as the whole portfolio. Mahara starts generating the export files and says "Export generated succesfully Continue". Then it displays the header image of our installation within the progress bar as can be seen on this image

Here are the error log messages:

Looks like some php functions have been disabled for security reasons.

Best

Hello Alex,

Which Mahara 1.3 version are you using?

Cheers

Hi Alex,

It looks like your server configuration is preventing Mahara from using the zip utility at the end of the export.

Cheers,

Francois
