Hi,

We are on centos 7.9

Can anyone tell me what I'm doing wrong or is anyone having the same problem?

When zipping the file manually I can view in the browser but uploading the leap 2A file in another mahara account results in a successful import of an empty template and an empty import folder in my files section....

Hi Emelie,

What version of Mahara are you using? When you import, do not only upload the Leap2A file. You need to upload the entire ZIP file because otherwise your files and other artefacts won't come along.

Thank you

We are currently using Mahara 22.04.2

When exporting the system fails to create the zip file. It stops at the point where the file is being zipped

16 December 2022, 16:01

Hi Emelie,

Can you please check your server's error log for any information? It sounds like you might be missing the PHP Zip extension.

Cheers

Kristina

We are not missing the zip-extension.

It seems to be a memory problem. When creating the zip-file, it seems to allocate a lot of memory. When zipping an portfolio that holds movies for example, the php-process crashes on memory.

We can manually zip the portfolio, but Mahara can't.

How does Mahara create this zip file and did anyone test this with movies in the portfolio?

16 January 2023, 22:43

These are our settings. The zip file usually breaks around 320 mb.

16 January 2023, 23:13

Also, is there a log somewhere that we can examine? We get no errors at all yet the zip-file never finishes.

Hi Richard,

Are you using the export queue or do you export portfolios straight away?

Thanks

Students are using MANAGE -> EXPORT from the menu.

Then they try to export a collection or even a page. When there's a lot of data on it (f.e. a movie) the export fails.

I don't see a queue anywhere.
