Hi
I have a web site using the Purity III template and am trying to update in readiness to migrate to Joomla 4
Current versions are
Purity III v1.1.7
T3 v2.6.1
Joomla v 3.10.11
I am trying to update using the JA Extension Manager component (v2.7.5 )
The Services manager JoomlArt Updates is set to default and marked online but every attempt to check for updates returns
Response from JoomlArt Updater Service: Sorry, this extension is invalid, unpublished or no longer supported: listplg_system_list_j16
Please update the service setting or contact with service provider.
Any help would be appreciated
