XF 1.5 I cannot upgrade to XenForo 2 (currently on 1.5.17) - Help?


Help. I don't know what to do. :/ While I'm upgrading, the update stops, safari says the page can't load to the network due to too much traffic, and when I reload and restart, I get this error.


edit: Since then, my forum cannot be accessed. So, in order to access it, I had to revert back to an old DB backup. I am now using XenForo 1.5.17, but would love to update to 2.0.2! When attempting to reinstall 2.0.2 after I recovered from my DB, I no longer get the original post error, it just doesn't work at all.

This is the page before I attempt to install. It crashes on step 43 with that error message. "action_available_via_post_only"

I just wanted to update to XenForo 2 ( the newest version).

I followed this introduction.

I used Filezilla to upload all datas from "download" to my server. It was succesfull with all datas, but I cant open the link for installation. :(

The site is currently being upgraded. Please check back later.
And if I want to install the upgrade:

Someone has an Idea? I am worried about my foro. :eek:

THX for help! :cry:
An AddOn for german language I think...

I just called 1&1 my hoster for server error log. They dont think, their is any error. They offered me a backup...

I upgraded some times XenForo 1, but upgrading to XenForo 2 seems to be hard. :oops:
On my first screenshot on the left is the folder "upload" from the XenForo 2 upgrade...

I uploaded it and replaced old files. The rest on my server are some icons, german-language-AdOnn, but I actually have just this AdOnn. Should I move the files to another folder you think?
Ok, I just called them, tomorrow I can talk to the technical support. I hope they can help me.

What they gonna find probably? Any experiences with this here? :unsure:

It's impossible to say - a 500 error is very generic so the log needs to be checked.

I'm surprised that you have to wait a day for that to be done though.

As an FYI, the URL for upgrading is install/index.php?upgrade/, not just /install/.
Lol, now I got it, Thx! :X3:

but next problems...

What does this mean now? :unsure:

Not yet, I think the rest is just about making some changes in Layout, Information-pages, Adsense connection, etc.

I think I will get this, most important thing, the foro works again. :)
Has someone an advice for a good Infopage-AddOn for XenForo2?

Imprint, etc. is by my old AddOn doesnt work anymore with XenForo 2...


Bump. I submitted a ticket but have yet to hear back in two days. Anyone else know the cause and how to fix it? Tried multiple times.
