I don’t know if it’s to facebook but whenever i publish, it delays a lot until it shows the internal server error then i refresh.
Another problem i am facing is that it does not import comments most times automatically, i have to resort to importing manually which is really stressful.
The most common reason for this is the amount of memory allowed for PHP on your server. Please check and make sure it’s not 32M or less. You need at least 64M, but if you have other plugins 128M or even 256M is recommended.
