I just installed the Flex template for Joomla and was working on setting up the various settings.
However, when I tried to save my first page of settings, it generated the following error message:
An error has occurred.
0 Error decoding JSON data: Control character error, possibly incorrectly encoded
Return to Control Panel
I can return to the Control Panel but if I try to access the template again I get the same error message.
Help! – Rik
PS: running Joomla 3.6.4
