Problem during upgrade IP Board from 3.4.x to 4.x

[fdanny15]

Hello!

I am trying to upgrade my IP Board forum from 3.4.7 to 4.0.13. I followed the instructions from this link and during the upgrade process I found this error:

Can anyone help me to solve this problem?

PS: I mention that this is a duplicate forum, because I don`t want to break my original forum, and I can turn back the process anytime.

Me and DumiCata finally solved the problem installing another version of ipb4 dropping core_notifications table while upgrading and the css is fully working.

Thank you for your helping!

When you do the upgrade, make sure you do not upgrade any applications.

Only upgrade Forum, Calendar.

Atleast thats the safe way i did it, i exprienced the same as you. Restored the backup redid the install but ONLY did Forum / System / Calendar.

No other things i upgraded and did those later after the install.

I tried to upgrade only Forum/System/Calendar, but the result is the same. I saw it would be a problem at notifications, because the table which has a problem is named core_notifications. Can anyone help me to make this upgrade fully working?
