This thread is resolved. Here is a description of the problem and solution.
Problem:
You are trying to install WPML but cannot proceed beyond the final step of the setup wizard. The 'Go to Translation Dashboard' button is unclickable, and the 'WPML → Languages' link displays an error message stating you are not allowed to access the page. Despite troubleshooting efforts like disabling plugins, switching themes, and adjusting server settings, the issue persists. The server logs indicate a PHP fatal error due to a redeclaration of the
wp_cache_switch_to_blog()
function in 'object-cache.php'.
Solution:
We recommend contacting your hosting provider and requesting them to disable the server cache and remove or rename the 'object-cache.php' file. This action should resolve the conflict causing the PHP fatal error and allow you to complete the WPML setup wizard. If the problem continues, please share the specific error message from your server logs with your hosting provider for further assistance.
Please note that this solution might be outdated or not applicable to your specific case.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 the issue persists, do not hesitate to open a new support ticket at WPML support forum.
