Hi,

I'm trying to update our Mahara from 1.7.2 to 1.8.1 and in my dev. enviroment ( maintained with git) I get the following errors on the dashboard after the login:

...........

[WAR] 80 (lib/view.php:2696) Invalid argument supplied for foreach()

Call stack (most recent first):

• log_message("Invalid argument supplied for foreach()", 8, true, true, "/home/feder/workspace/Mahara/htdocs/lib/view.php", 2696) at/home/feder/workspace/Mahara/htdocs/lib/errors.php:430
• error(2, "Invalid argument supplied for foreach()", "/home/feder/workspace/Mahara/htdocs/lib/view.php", 2696, array(size 10)) at/home/feder/workspace/Mahara/htdocs/lib/view.php:2696
• View->get_layout() at /home/feder/workspace/Mahara/htdocs/lib/view.php:1776

• View->get_all_blocktype_javascript() at /home/feder/workspace/Mahara/htdocs/index.php:35

........

This occurs , as I mentioned on the login dashboard and when I want to open a view...

Below the error message the dashboard site also the view is displayed properly. 

I installed a "fresh" mahara 1.8 to compare the files, but there are no differences..

Has anyone an idea or hint..?

Thanks in advance!

Hello Christian,

I would recommend to make a compare-check of the database scheme, between your installation and a fresh Mahara 1.8.1 installation.

You will then maybe find some changes in the database scheme that must be addressed on your side.

Hi dajan,

this error has gone in the meantime.. ;-)

While I was comparing the schemas, I implemented v1.8.2 today and the are no more errors in my enviroment!

To the comparison of the schemes..

I'm not sure, if there is a mor convienient way like I did...:-(

...to compare the DB-Schema, i made two (schema-)files with pg_dump, then i created a .diff file ( >700MB, and >64000lines).

This is very challenging..

Regards,

Christian
