hey ronald,
as you're on easyblog 3.0 in this case the auto-updater doesn't work. To update to the latest 3.9.x version you need to manually install the latest package.
in general the auto-updater only works within the same major number, so when you're on 3.9.x you can always use it to get the latest version as long as the latest version is 3.9.x.x - when it's 4.x then again it won't work.
hope that helps

Thanks Alex - I'm pretty new to this and would be very grateful of a quick run through of what a manual update is made up of? Will I still be able to keep all my previous blog posts etc?

hey ronald,
sure, I'll try to help out.
a manual update only means that you would have to upload and install the easyblog package as you would do with any other joomla extension as well in your joomla backend -> extension manager. you could also do an uninstall of your current easyblog version first (some recommend this so you don't have unneeded old leftover files) before installing, but both ways (with or without uninstall) would work.

your existing posts are stored in the database so you won't lose them (even with an uninstall) but of course if you made some customizations on the easyblog files itself these will be overwritten with the new install.

usually it's a real painless process, however always do a backup first! so in case something unexpected wents wrong you can safely go back to a working system. hope that helps

Thanks for sharing Alex By the way, if you are still having troubles upgrading, let us know.
