Hello,

First you need to make sure that you have made all the customization to the child theme not to the main theme. So when you will update then the customization will not be lost.

Please update the theme and the recommended plugins first. Then Regenerate CSS from WoodMart >> CSS Generator.

Then disable server caching, deactivate cache plugin, clear browser cache and check back.

If the problem continues then tell me we will troubleshoot with theme plugins.

Best Regards.
