Update page Freeze and Error

Hi,

I think this issue is related to my other one (https://support.ishyoboy.com/forums/topic/colours-changing-without-sense/)

EVERYTIME I update a page or a post, the WP admin screen Freeze for a moment then diplay either a Connection issue or simply freeze for ever.

This is happening only with BOLDIAL theme and I have no other plugin activated which could interact with the visual editor.

Thank your for you support.
