We're aware of problems with EBSCO and are working to resolve them, but we cannot reproduce any errors with Blackwell Synergy. Could you please provide a specific example or URL that is failing?

Here's a Blackwell Synergy URL that fails:
http://www.blackwell-synergy.com/links/doi/10.1111/j.1520-8583.2004.00032.x/abs/

Zotero just gives the old blank box on trying to capture the reference here - same as I see regularly when I get failures trying to capture references via EZProxy. Also, no new errors are reported via the gear icon. Is there any way you could make Zotero more informative when it encounters this kind of problem?

Further info:
The current Blackwell Synergy translator assumes URLs of the form:
http://www.blackwell-synergy.com/doi/[ACCESS TYPE]/[DOI]

(ACCESS TYPE may be: "abs" OR "full" OR "pdf")

It doesn't recognize the form I used (from an external link):
http://www.blackwell-synergy.com/links/doi/[DOI]/[ACCESS TYPE]/

Hope that helps.

These problems have recently been fixed. Please update your translators.
