If I want to create a new article for my onlineshop I get allways the error message
Uncaught TypeError: Cannot read property 'openBox' of undefined This must be a java script error.

I want to create a new article in my onlineshop. When I want to klick on the right side of the window to the add button then there will no open a new window. So I can´t input new article.
It´s also the same with existing articles. There is no way to change somthing.

I hope you can help me

Hello Jerome
I have created a new article in the online shop named "blabla" you can check with this article or you can create a new one.
You can click on every right sided button you found there is now way to create a new little window to change somthing.
delete with the button functions. But no way to "hinzufügen" no price no option no picture nothing. The Server is on the newest version
from joomla and application and plugins. The message cannot read property "openBox" comes from the provider all-inklusiv where the website is hosted. For my knowlegde I have created with a new template 3 weeks ago. The template comes from a german company named www.joomlaplates.de/ultimate before I had the template Allrounder from www.lernvid.com which has died theres no way to work with this side. So I have bought the new one from joomlaplates.
You can loggin to the side
But think it`s my liveside I will do at the moment a backup with akeeba .

Good morning Jerome
Yesterday after I read your message I had a look into the directory media on my server
and I have found the following look to the picture I will send .
There are 2 files hikashop.js and hikashop.js-old in the same directory.
The second file "hikashop.js" has the time stamp from the update from your software,
so i am thinking it is right. the old file has the time stamp from october. I could not recognize
that i have something changed on the file.
What can I do now ?
A new installation over the old installation,
or
can i change the 2 files by renaming it.
this means mv hikashop.js to hikashop.js-new
and hikashop.js-old to hikashop.js

kind regards

Hello Jerome

I have downloaded the hikashop this morning
Do you mean the hikashop.js file from directory media which I should copy to the server.

I have copied the file which I have described above but it didn't function.
If you click on the add button it shows nothing. the same as before.
Should the provider reboot the server or the homepage www.b-em.de ?

kind regards

Sorry it was my mistake with the error.
I have found the error i have done. It cames from google webmaster,
they mean you can save 1,1 kB of Javascript if you decrease this file.
So I have done it, and have lost the normal working java file.
I have written this for other users which have the same problem with google ans page speed inside.
I'm terribly sorry that I had to harass you

kind regards
