I am installing and activating Sharepress on a single blog within a multi-site installation. The domain of my blog is a different domain from the root site via Domain Mapping. I have multiple plugins on the site and there have been no problems so far.
When I activate the plugin, I get the following error:
Warning: strpos() expects parameter 1 to be string, array given in /[my site root]/wp-includes/link-template.php on line 2027
Is this a result of multi-site, of the domain mapping, or what else?
