Background of the issue:
I am trying to resolve PHP errors with WPML 4.7.2. I was attempting to use the plugin when the issue occurred. The issue can be seen on the page: versteckter Link.
Symptoms:
I expected to see no errors, but instead, I got multiple PHP errors. These include 'PHP Fatal error: Uncaught Error: Call to undefined function wp_cache_get()' and 'PHP Warning: include(): Failed opening...'.
Questions:
How can I resolve the PHP errors with WPML 4.7.2?
What is causing the 'Call to undefined function wp_cache_get()' error?
