Joomla: SyntaxError: Unexpected token I in JSON at position 0

If you use the CMS joomla, the following error message may occur with certain components or modules: "SyntaxError: Unexpected token I in JSON at position 0".

A syntax like: "SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data." If you have such an error in your Joomla website, we would like to give you a hint on how to fix the problem.

The main reason for the JSON error is very different, and usually depends on the programming of the affected component, the module or the plugin. A partial cause, with which the error but can be remedied is however usually the cache.

For this reason, we recommend the following. Solution for "SyntaxError: JSON.parse" in Joomla :

  • Disable Cache

First, disable the cache using the backend:

  • System -> Configuration -> System
  • Set Cache to "Off"

To fix the bug the page cache must also be disabled. To do this, open in the backend:

  • Extensions -> Plugins
  • Search for "page cache" and deactivate the corresponding plugin.

From now on, you should not get an error in Joomla with "SyntaxError: JSON.parse: unexpected character at line 1 of column 1 of the JSON data".
