Please have a look at this installation guide.

This points to your server having low limits with respect to permitted upload times. Please set the values in the php.ini file to 90 for “max_execution_time” and to 48MB for “post_max_size”.

If you do not know how to do it, please contact your server support / hosting company for that (we would do it ourselves for you, but we cannot do it, it is a server thing).

Alternative ways to upload the plugin:

A. With File Manager plugin, see more info here.

B. Via FTP:

1. Unzip the plugin on your computer, which will uncompress all files. They will most likely be in a folder whose name is the same as the name of the plugin.

2. Upload that plugin’s folder via FTP to your website’s wp-content/plugins/ directory. Once it is there, you will be able to install the plugin from your plugins admin page when logged in.

See some training on FTP

Please ensure that you are actually uploading the zip-file you received after downloading.

On Mac sometimes the file gets unzipped automatically. In this case, either zip it again (right click on the folder and select “compress”) or prevent the automatic unpacking by your Mac, see here.

This error message points to the fact that you still have the PLUS plugin installed. Please delete it, and then try to install the Premium Plugin again.

This means your server has difficulties communicating with our server. In most cases the reason for this is that there are restrictions on outgoing connections on your server, e.g. because of a firewall. Please ask your hosting company / server team to either a) temporarily de-activate the firewall (port 443) for a minute (at least the outgoing connections) or b) whitelist 188.165.53.179 and 192.81.249.240 as IPs so that your server can communicate with our server.

Please:

1.) Install the plugin on the parent site but do not activate it

2.) Activate it on the child site where you want to use it

Please ensure that:

• You do not still have the PLUS version installed (please delete it entirely from your system)
• You are using the latest version of the plugin(s)
• Your site is running on PHP 5.4 or above 
• You have CURL activated (should be activated by default)

If you are not familiar with those, please contact your hosting company or server admin.

Please check if you have browser extensions activated which may conflict with the plugin. Known culprits include:

• Open SEO Stats (Formerly: PageRank Status) – Chrome
• Adblock Plus – Chrome
• Vine – Chrome
• Optimizer.io
• RegistrationMagic
• Woo Order Note template

Either de-activate those extensions or try it in a different browser.
