The link you follow has expired

If you encounter the error message “The link you follow has expired” during plugin installation process, you will need to increase some PHP variables.

This happens because files size is larger than your PHP variable upload_max_filesize. You will have to increase your upload_max_filesize to a value larger than your files size. 

As more features are added to the plugin, the file size will increase over time. Therefore, you may need to make adjustments when you install a new version.

In this case, please contact your web hosting company for help to increase the followings values in your php.ini file

upload_max_filesize 200M
post_max_size 200M
max_execution_time 1000
max_input_time 1000

You should be able to upload install now

Alternatively, you may install the plugin via FTP
