When i try to edit my posts in the joomla frontend i get the following error:

Uncaught ReferenceError: Joomla is not defined

I can open the posts editor in the frontend, change the content and when i want to save it i get another error:

Uncaught ReferenceError: Joomla is not defined at HTMLButtonElement.onclick

How can i solve this problem? Looks like a script or something is missing. Im using Joomla Version 3.6.4, use a frontend built from scratch and my admin template is isis.

There can be javascript cache problems.
Clear your browser/Joomla! cache first:
https://docs.joomla.org/Help36:Site_Maintenance_Clear_Cache
http://www.wikihow.com/Clear-Your-Browser's-Cache
If that won't help simply reinstall Joomla! Keep in mind that all your CSS changes will override during reinstallation.

  • Thx for your help. I clearad all the cache. Nothing changed. I think also a joomla reinstall will not change this. Someone told me it could be that mootools ins not loaded. Now i try to load mootools with joomla. I added "('behavior.framework')" and also installed a plugin to load mootools. Actually its doing nothing (not loading mootools). Going crazy about this... – Peesen87 Nov 9 '16 at 10:16
  • As for mootols plugin, have you tried: plg_j25_legacy.zip plugin? – micjan Nov 9 '16 at 10:20
