Oh oops! Sorry, I did receive a solution a few months ago but completley forgot about the email! Their support is actually quite good. Super sorry!
Hey Ilan,
It looks like you are still running an older version of at least our JavaScript (see attachment). I’d like to help you get updated to our new JavaScript to see if that maybe solves the problem, because we’ve made a lot of little changes in the plugin since version 6.0.0.3.
Please, follow along with this article for instructions on how to perform a clean install, which includes details on removing our plugin’s settings from your database: https://support.shareaholic.com/entries/23341971-How-to-Perform-a-Clean-Install
Make sure you clear and deactivate any caching plugins before performing these steps and while we troubleshoot, so that nothing gets in the way of the plugin retrieving the updated files from our server.
Also, verify that your Custom Path to Shareaholic File Resources (under the Compatibility Settings panel on the SexyBookmarks options page) is correct. You can use this article as a reference: https://support.shareaholic.com/entries/23355347-How-do-I-fix-the-spritegen-directory-write-errors-in-WordPress- (see the notes at the bottom)
Clear your browser’s cache and preferably restart it, then check a random post on your site to test for the button visibility issue. Let me know how this goes. Thanks and good luck!
Going to try this now.
