Dimitrios Vasileiou

Problem:
The client set English as the default language by mistake and wants to make Greek the default language, with English as a translation. Despite re-adding the plugin, the issue persists, and the pages created in Greek display in English.
Solution:
If you're experiencing an issue with the default language setting in WPML, we recommend changing the default language by following the instructions in our forum post: Changing the Main Language.

Simply uninstalling and reinstalling WPML will not change the settings, as they are saved in the database. If a full WPML reset is necessary, please follow the steps outlined in our documentation: Deleting Languages and Plugin Data by Doing a WPML Reset on Your Site.

Please note that the solution provided might be irrelevant if it's outdated or not applicable to your case. We highly recommend checking related known issues at WPML Known Issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the issue persists, we encourage you to open a new support ticket in our forum for further assistance: WPML Support Forum.
