Hi Martin,
Could you please check whether the issues are still occurring now?
For the preset color issue, please follow these steps:
- Go to Helix3 → Advanced.
- Enable Compile LESS to CSS.
- Save the template.
- Disable Compile LESS to CSS again.
- Save the template once more.
- Clear the Helix cache, Joomla cache, and your browser cache.
I also noticed that your hosting appears to use server-side caching. Please clear the hosting cache as well, then check if the dropdown menu background and link colors have updated.
Let us know the results after trying these steps.
