Hi,
We updated the home page, it looks fine for 5.4.7, but did you already tried to update the site to 6.x RC on a DEV server?
New versions of plug-ins (from SEBLOD.com) will be released as well, but of course if you see one that is not yet and is required feel free to report.
By the end of the month, we will release the 6.x GA release, and we would strongly suggest to update to Joomla! 6 and SEBLOD 6 in order to get the newest updates.
There will be no more release for SEBLOD 4.
Saba
