Few problems

Hello guys,

My website o3leeuwarden.nl was shown perfectly while using this theme. Until now; some pages doesn’t show and the homepage is incorrect at the moment (while in dashboard everything is shown well). The only thing you see at the homepage is Projects, while there are many more things like “Missie en Visie” and “Huidige Stagiairs”. These things aren’t shown correctly. Strange enough it was good before.

Another problem is that I can’t update wordpress to a next version. The following error occurs;

Downloading update from https://downloads.wordpress.org/release/wordpress-4.3.1-no-content.zip…

Download failed.: Failed to write request to temporary file.

Installation Failed

What can I do and how can I solve these problems? Thanks in advance!

Does anyone got an idea to solve this problem?

Thanks in advance!
