Hey stan_va,
I didn't find an exact solution, but I noticed that the new version (1.7.1.2) reports they have fixed it:
Some of the most notable fixes are:
Add a scrollbar for editor
etc...
Full list of changes: http://build.prestashop.com/news/prestashop-1-7-1-2-maintenance-release/
The One-Click Upgrade won't work for me, so I can't test it unfortunately.
I'm getting the following error:
PrestaShop Original version:
Error Unable to check md5 files
If anyone has a solution for that, I'd love to hear it.
Hopefully this helps you a little, though.
Eric
