empty: /index.php/dashboard/extend/install/

Permalink
Hi

what can I do if /index.php/dashboard/extend/install/ shows only an empty page?
I THINK (but definitely not sure) it has something to do with some Add-On.
Right now I feel, I can not even see the addons anymore, so I am searching your help.

Is it showing any error in console? If so, check which add-on do this and remove that add-on.

Hi Rony,

console? What do you mean? Can you show me an URL please.

If you are using Firefox, then install Firebug. It is a developer tool that will help you to see the error. If you are using Chrome, then simply press F12 and click console tab.

Hi

well, great.... the console is showing:
"NetworkError: 500 Internal Server Error -http://www.blablabla.de/index.php/dashboard/extend/update/"...

I am a bit speechless as the page in general works.

Hi Rony,

thanks for your tip with the console window.
This solved it. After discovering the "NetworkError: 500 Internal Server Error -http://www.blablabla.de/index.php/dashboard/extend/update/"... I looked at the error log on the server. This shows that a theme (I created a backup from) tried to redeclare a class.
I removed the bckup - site works fine again.
