Problem: You are trying to ensure that the CSS for the English and Dutch versions of your site are consistent, but currently, they appear different. Solution: First, determine whether the CSS differences are due to custom CSS you've added yourself, or if they stem from your theme or a plugin without additional settings. We recommend checking the setup of your CSS for both language versions. If you find that the issue persists and the setup seems correct, it might be necessary to adjust the CSS manually to ensure consistency across different languages.
If this solution does not resolve your issue or seems irrelevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If further assistance is needed, please open a new support ticket at WPML support forum.
