Hello,
we have mentioned a bug with the WP External Links plugin. Is there anything already known about this?
When we edit a page we get the following error: “Updating failed. The response is not a valid JSON response”.
We followed various instructions, which unfortunately were unsuccessful. Finally, we deactivated all plugins, tested page editing and gradually reactivated the plugins. We noticed that the error only occurs if the “WP External links” and “Smart Slider 3” plugins are activated at the same time. This behavior leads us to suspect that there is a conflict between the two plugins.
We have installed the latest versions of the plugins:
WP External links: 2.59
Smart Slider 3: 3.5.1.21
Thanks for your help!
