    • If you have updated to J3.6.3 and are receiving a "Error decoding JSON data: Syntax error" error then please read the following.

      There was a little error in a JSON string for the presets in the template - we have now corrected this but for existing sites you will need to use PHPMYADMIN to edit the database to correct his...

      Please replace the "#" above by your table prefix.

      The database will then be corrected and your site should then be ok.

      For other "generic" JSON string errors that have manifested themselves after J3.6.3 or later update...
