I have been working with joomla for many years and had no issues with the following until today.
I download new templates, attempt to install them and get the following error:
Error! Could not find a Joomla! XML setup file in the package
If I try to install a template I have previously downloaded, I have no issues.
I have tried downloading templates from different sites
I have tried installing newly downloaded templates to several of my joomla sites
I have no issues with templates downloaded prior to today
I have tried different PCs
Any advice welcome...
