I discovered that this issue of main menu moving left and right between pages loading is caused by a conflict of Elementor plugin and the Re-Dokan theme. Is this something you can help me with to fix or must I ask Elementor?
See video clip to remind you of what happens between pages loading with main menu https://www.dropbox.com/s/qkb2vgeqskmq1tz/img_2417.mov?dl=0
I deactivated all plugins with only woocomerce and theme in place. Menu does not move left to right. With elementor activated again it starts problem.
