Can't retrieve citation numbers

[leido]

I followed the README install instructions for zotero standalone, but most papers don't show the citation number.

I saved most of my papers from arxiv.org.

I use firefox 49.0 and zotero standalone 4.29.0.10 under linuxmint 18.

I have the same problem in my computer.

Plugin has stopped working for me (now gives citation count 0) on zotero standalone for mac.

This could be an issue with Google blocking the requests the plugin is sending. Try going https://scholar.google.com/ in a 'Private or 'incognito' window, and see if you are challenged by reCaptcha. if so, the program is working, but Google is blocking the automated request.

EDIT: I'm also using standalone on Mac, and when I get the reCaptcha, this plugin does not open a new windows for me to solve it. Does the program open a new window for you?

I have the same problem, and the Captcha did not show (Stand-alone version). I tried to navigate to google scholar in both Ingonito mode and via the browser in the stand-alone version, but none appear. I also installed it on another computer and it is still working fine. Do you have any idea to debug this problem?

The same for me. Google blocks it and I am not even able to export bibetex from google scholar as well. The result is the same after the Captcha. The message I got is:

Your client does not have permission to get URL /scholar.bib?q=info:JmnKBgM_caIJ:scholar.google.com/&output=citation&scisig=AAGBfm0AAAAAW2rfmMAz0IPoLsL3oRLPe37gMKtvL-Qu&scisf=4&ct=citation&cd=-1&hl=en from this server. (Client IP address: xxxxxxxxxxx) Please see Google's Terms of Service posted at http://www.google.com/terms_of_service.html That’s all we know.

It is a shame, because the plugin is awesome and I like it very much. Maybe a change of IP will suffice, or not to do more than 1 at a time.
