XF 2.1 Unknown tag fa encountered.

[Halt03410]

I just recently upgraded my forums and botched hard. Initially my forums were not forums after the upgrade, just looking like a bunch of XML plain text so I went into the admin panel and saw the following

There are manual rebuild jobs awaiting completion.

but every time I attempt to rebuild I get this error

Unknown tag fa encountered.

So I hit up Google and saw that some old addons might prevent the upgrade process from going smoothly. So I removed all of them but still run into the same issue. Any ideas?

It sounds like a style related issue, try setting the board to a default unedited style.

I set the boards default style and got the same error. This is the setting you were speaking of right?

Setup > Options > Appearance > Default

What is your forum URL? I'm currently unable to find an up-to-date license for you.

There doesn't seem to be any website hosted at that URL. That is the URL on your license but do you have another license or are you using that license at a different URL?

 

[Halt03410]

No sorry my license is at

https://forums.blacksunstudios.us by habit I initially typed my old domain. I realized that my license had expired after you mentioned it. Figured that was the issue.

Thanks for the update.

I think this has happened because you have attempted to install an add-on designed for XF 2.1 on XF 2.0.

Starting with 2.0.10 we made some changes that might not block these rebuild jobs. You can kind of read more about that here:

XF 2.0 - Blocking template syntax error when installing a newer add-on on older XF

Hi :) a few days ago by mistake I tried to install @Brad Padgett [BP] Light Switch and Style Chooser add-on, I'm using Xenforo 2.0 and the add-on I was mistakenly trying to install is for xenforo 2.1. the add-on is not installed and an error has occurred Line 179: Unknown tag fa...

xenforo.com

So if you upgrade to a minimum of XF 2.0.10 then it should solve the problem.
