I decided a while ago to start again with my AbanteCart store but never did much to it thanks to some health problems, so it wasn't a big decision late night Australia time to uninstall 1.18, after admin upgrade attempts failed, and then install 1.2 to start again, again. But the same logo I use on my current old free CS Cart site & used on both AbanteCart sites I started & stopped on is WAY too big on 1.2. I have resized it to no avail, it still shows as huge, covers most of the header area. I have checked in my cpanel & the size etc for the logo match what's in my first attempt's stylesheet (will uninstall this 1.17 when I have 1.2 how I want it, looks like another learning curve though).
And re the failed upgrades, yes my cpanel has all the suggested PHP versions & mysql & mysqli checked, so my host is very good.
