Hi Lara – am I right in thinking that the automatic update is not working here (and if so, have you definitely entered your license keys in Events > Settings)?
If that’s all in order but it still isn’t working you may need to handle this either by FTP, if you are familiar with that sort of tool, or through your web hosting control panel and its file manager, if one is provided.
The idea would be to backup your site first of all then deactivate the old versions, optionally put the site into maintenance mode if you want to use one of the many plugins available for that, then delete the old plugin directories (only for the plugins you are going to replace – Pro and Community). Then, upload the new versions.
Make sure they are unpacked/unzipped once they are uploaded. Finally reactivate them (and take your site out of maintenance mode).
Does that help?
