Hello,
We fixed the problem with constantly reloading of single item when slide show auto is enabled in v. 1.8.3. It looks like a problem with Facebook comments because the slide refreshes constantly and reload comments. Please update the plugin.
About problem with share image, it looks like a conflict with 3rd party plugin. It works fine on latest WordPress version on fresh installation. We can investigate this problem if you provide a temporary access to your WordPress backend by
email. If it is not suitable for you, we can provide the refund.
Regards,
ARI Soft
