I’m having a weird problem, sometimes when I launch the site, the menu font is bold. Then several minutes later if I reload the page the menu goes back to the font that I like, that is to say NON BOLD.
Please deactivate all the plugins except these ones:
Slider Revolution
WPBakery Page Builder or Elementor
Woodmart Core
Contact Form 7
MailChimp for WordPress
WooCommerce
Safe SVG
Switch to the parent theme and check.
If the problem has gone, activate the plugins one by one, checking the issue to detect which one causes the problem.
