Hi Laura,
Yes, I think it must have been something to do with the social articles plugin update or the new kleo theme update. Before these two new updates on Friday I wasn´t having any issues. Did other users flag up similar problems with social articles and kleo theme over the weekend?
There were two new updates to the same plugins yesterday which I installed and since then I haven´t seen the error messages. However, my site appears to be running a bit slower than it was previously.
I would appreciate if you could let me know if there were known problems with one or both of the plugin/theme so I know what has been going on.
Many thanks,
Adam
