Reported for: WPML Multilingual CMS 4.5.0
Resolved in: 4.5.3
Overview of the issue
Since WPML 4.5.0, our WPML Translation Management add-on is a part of the core plugin. This decision reduced the number of plugins to install and keep up to date while maintaining all the same functionality you had before. However, it also increased the size of the plugin itself.
Many WordPress hosting companies have settings that control the size of files you can upload from inside the WordPress admin area. If these settings are set too low, or you are trying to upload a larger plugin or theme, you see an error that states, The link you followed has expired.
The easiest way to fix this error is by increasing the file upload size, PHP memory, and execution time limits for your website.
If you have some control over your hosting, you will find this WPBeginner tutorial helpful. Otherwise, we recommend you reach out to your hosting company and ask them to do this for you.
In the meantime, you can also upload your WPML plugin using an FTP client.
