Sometimes hosting providers display incorrect information about what version you are running and you need to install the health check plugin to verify.
If it is not greater than 5.3.3. You need to contact your hosting provider for them to upgrade. PHP 5.3.3 came out in 2010
When trying to activate the plugin I am getting: –
Parse error: syntax error, unexpected ‘add_filter’ (T_STRING) in /data01/c9104702/public_html/humanrev/wp-content/plugins/landing-pages/modules/module.clone.php on line 1
your ftp client might be mushing the code together.
This happened to me using Filezilla. You need to set the data transfer type to binary.
Some times your software installation might not work because you need to transfer your files in Binary . This video shows you where to change the transfer type in filezilla.
