This thread is resolved. Here is a description of the problem and solution.
Problem:
You are unable to add a new custom language to your site, as the process times out despite increasing the max execution time.
Solution:
If you're experiencing this issue, we recommend you follow these steps:
1) Update your WPML plugins to the latest versions. Go to Plugins > Add New > Commercial and click “Check for updates”. Please ensure you create a backup before updating.
2) Disable Reds object cache and attempt the process again.
3) If the problem persists, try switching to a regular WordPress theme instead of a custom one to rule out any issues caused by custom code. You can do this by switching to a WP default theme and checking if the issue still occurs.
If these steps do not resolve your issue, or if the solution seems outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent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 you still need assistance, please open a new support ticket at WPML support forum.
