XF 2.1 Site broken after upgrade

[Finexes]

Heys guys,

my site is completely broken after upgrading to 2.1.10 Patch 2. That's the first time this is happening after upgrading.

The following error is displayed in my adminCP:

Server error log

    XF\CssRenderException: Error rendering template public:core.less: Expected ')' got '2' in public:core.less (on or near line 6463) src\XF\CssRenderException.php:87

Admin pages are perfectly fine, but my style itself is all messed up. I already tried disabling all add-ons, that doesn't work either. Any suggestions? :/

Try on a default style.

Hi Ozzy,

thanks, default style is working.
I noticed a bad entry in one of my style properties. After reverting, everything started working again
