Background of the issue:
I installed the WPML plugin on my website hidden link and deactivated it afterward. After that, I added pages and products. When I activated the WPML plugin again, all those pages and products didn't show anymore.
Symptoms:
Pages and products added after deactivating WPML are not visible after reactivating the plugin, although the number of pages is visible in the information bar.
Questions:
Why are the pages and products not showing after reactivating WPML?
How can I make the pages and products visible again with WPML activated?
What you're experiencing is normal. During the setup wizard, WPML assigns a language code to all content. However, if you created content while WPML was deactivated, it couldn’t receive this code. Now that WPML is active again, that content is in a sort of limbo—it exists, but you can’t see it because it has no language code assigned.
To solve the issue, go to WPML > Support > troubleshooting and click on "Set language information". Note: All content without a language code will automatically be set to the default language.
