XF 2.0 Noob here, server just stopped working a few days ago and I keep getting this error in the log

[_reg]

I have no idea how to fix this, I haven't changed anything so I suspect this was an automatic update that broke something. Any ideas how to fix?
Please give steps, I'm pretty new to this aha

@primaryLighterStill is a XenForo 1 style property which doesn't exist in XF2. You also shouldn't be able to import an XF1 style on XF2. Did you recently upgrade? On upgrade they attempt to keep the color values, so may be a bug in that process if that's the case?

Haven't recently updated or even touched the backend since way before this happened and I'm not using a style or template I don't think :L

Do a template search for '@primaryLighterStill' - that should identify which template it is in, possibly extra.less.

Thanks, I just cleared this from my extra.less but it seems like it's still not working.

I don't know if this is a clue but what happens when I try and open my website is it redirects to mysite.com/forums/install/app.php

 

[Paul B]

That's most likely unrelated to XF.

Possibly something in .htaccess or even at the server level is causing that.

Just bumping this with my .htaccess if anyone can spot what's wrong

Edit: Apparently it's stuck in a redirect loop, anyone know how that could happen?

That looks to be a htaccess from phpBB.

In the root of your XenForo install you should see the default XF htaccess named htaccess.txt, rename it to .htaccess.
