Yep I can confirm this on both my sites (Multisite each in english and romanian) Sfaturi IT and Diverse Lucruri (I am in testing so this doesn’t affect me much)
I’m on nginx and the error is 500(Internal server erorr) ” Call to undefined function is_product_category ” on shareaholic/utilities.php on line 354 and the affected line is // elseif (is_category() || is_author() || is_tag() || is_date() || is_product_category() || is_product_tag()) // I think that both functions is_product_category and is_product_tag are undefined.
Probably your feed site.com/feed/ will not work(If you have some service depending on your rss feed you should check it out). It didn’t for me, also when I tried to post I was receiving a white screen, but the posts appeared on my site…
My solution was to downgrade to shareaholic.7.5.1.0 util the problem is fixed, but I thing that if you replace the line with // elseif (is_category() || is_author() || is_tag() || is_date()) // it should work..
