Theming App 1.4.4

Hi there,

when i update the Theming App from 1.4.1 to 1.4.4 (in order to meet the new GDPR requirements) the whole front-end is broken. (see the Picture).


So, i downloaded the newest Version of the app,
unzip it and copy it into the app Folder.

As soon as i refresh the page, it asks me to reconfigure the site which semms to be nessesary for the app theming to complete.

The result is the broken front-end as shown in the Picture above.

What am i doing wrong?

Thank you for your help!
