So I think that the issue is in server timeout error or in max response size ( your plugin generates very huge controls config when loading elementor front-end builder ).
Looks like I know that causes the issue – very huge config for Elementor module controls that loads via ajax requests. My question is – are there any php hooks that I can use to disable some of ThePlus modules options ( styling options most of all )?
Or you have another solution how to make these controls config smaller?
