I have just tried to ugrade to newest version 0.6.14100 (light) but such error occured:
I have several products with custom attribute set defined.
Deleting Core/GiftMessage directory makes store working (except orders admin area)
Ok, in order to upgrade to the latest version you can just temporary rename that group as it was by default - ‘General’, put the GiftMessage module files in their places, upgrade and then change that group name back to âOgÃ³lneâ.
The problem is that new attributes are added to the attribute group “General” by its name. We’ll fix this in the next releases.
Thank you, thank you, thank you. I was having a catalog wrong attribute ID error, that’s been crashing my site for the 4 days. replacing *.abc for *.php cleared up the issue. It didn’t solve it, but at least my site works now.
