I am running EE2.6.1 and want to upgrade my Playa addon from version 188.8.131.52 to 4.4.5.
I was running into the same errors as posted previously here, then reverted back to the previous Playa version and tried again.
This worked locally, but not on my production install.
I followed the upgrade instructions by replacing both folders and going through Add-Ons > Fieldtypes > Playa to run the upgrade script.
When I examined the database through phpMyAdmin, I could not find any column
parent_is_draft in either database - local or production. However, the local EE install shows "4.4.5" in Add-Ons > Fieldtypes > Playa, while the production install shows the old version.
For the time being I've rolled back to the old version. What steps can I try next?
Edit: Just like reported here I see different versions: When going to Add-Ons > Modules > Playa, EE shows "4.4.5".
