Hi,

I have just upgrade to IPS4.1 from 3.4.8 and all the process was ok

But now I have only the A Test Forum and some other default datas.

All my forums and members don't appear.

I still can find the ips database with all the datas (and modified by upgrade) but nothing on backend and frontend.

Could somebody help me ?

Thank you!

 

did you do http://domain.com/upgrade or http://domain.com/install?

Yes you are right...

I did the install 

I restored both database and files, and get my 3.4.8 installation working fine

Then I do the upgrade and got this error : 

 

I re restored database and click on fresh upgrade but at the end I get : 

 

 

Click continue. 

I tried it but I get an error too

So I decided to restore the whole site and then ask IPS staff to upgrade

Do you think I should retry the upgrade and click next to all this kind of errors ?

Is it normal to get these errors upgrading to 4.1.5.2 from 3.4.8 ?

Other users had the same problem : https://community.invisionpower.com/topic/408349-step-7-error-during-upgrade/

I had a few errors when trying to upgrade also. What I did is I let the upgrader hang on the error page and re upload the files via ftp. Then I clicked on "retry".

It was a little painful but I got through it.
