Problem: You want to add HTML 'alt' attributes to flag images in the language switcher on your WPML-powered website, but the current setup only allows modifications directly in core files, which are overwritten during updates. Solution: Currently, there is no permanent solution to add 'alt' attributes to flag images without modifying core files. We acknowledge this limitation and have detailed the issue here: Missing alt tag for flag image in a language switcher.
If this solution does not apply to your case, or if it becomes outdated, we recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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. Additionally, if you need further assistance, please open a new support ticket at WPML support forum.
