Hi X Theme,
When I try to save a page using the wordpress editor - I am doing this in order to add a featured image - I get this error:
Updating failed. The response is not a valid JSON response.
I turned off all plugins and turned them back on one by one and it is revolution slider which causes it.
I deleted rev slider and reinstalled it from the pro menu.
The issue still occurs.
I have also removed the classic revolution slider blocks from the page and readded the sliders using shortcode.
The problem persists. If I turn off rev slider plugin then the page saves fine.
Can you help?
