Hey @yvescleeren,
Just letting you know, bumping or replying to your thread bumps it down the queue as we answer threads from oldest to newest. Please refrain from adding on to your replies if you can.
Regarding your header, it’s the [xoo_wsc_cart] shortcode causing it not to save. Try inserting that shortcode in a Global Block and insert the Global Block shortcode in the header instead of inserting the cart shortcode directly. If you’re not yet familiar with global blocks, please learn the usage here https://theme.co/docs/global-blocks
When reporting an issue to us, please first do the basic troubleshooting listed here https://theme.co/docs/common-issues. That is because if we’re going to be the one to test for plugin conflicts, not only will it take time for us to know what plugin is conflicting with the theme, some plugin settings might reset or we might miss activating back an important plugin. This will also will not be good for you and the rest of our customers because this will mean that you will wait longer because we’ll be troubleshooting hundreds of sites when usually, the culprit is a 3rd party plugin or custom code that is not well made.
By the way, I updated Pro too and your header didn’t break.
Thanks.
