After updating wordpress to 3.61, I began to have the following issues in this specific order:
1. Click any portfolio item on the front page, Ajax lightbox executes normally, loading graphic repeats and portfolio images never load.
2.Exit out of the ajax lightbox, click on any other portfolio item, ajax lightbox transition executes and immediately closes–failing to show the portfolio item within the lightbox. Entire site then becomes unresponsive.
Please update Eunoia to the latest version as well. You are currently using version 1.3. You should login on ThemeForest with the account you have purchased Eunoia with and go to Downloads to download it
