Hi Dek Ery,
thanks for your suggestion. Only the plugins required by the theme are active.
I would like to point out that with the previous version of the theme (2.3.1) and Visual Composer 4.5.3 the problem did not arise.
I noticed that with ‘Animation speed’ set to ‘Fast’ or ‘Slower’ everything is ok, the issue occurs with Grid Animation enabled and ‘Animation speed’ set to ‘Slow’.
I have to correct what I wrote regarding Jkreativ – Portfolio block items: the animation here works.
Instead I confirm the problem with ‘Default’ button in jkreative callout element.
Can you do anything about these issues?
