I have had for some months installed WPeMatico plugin that I use often. But the last few days it began to behave strangely, I started getting some serious error messages like:
[DEPRECATED] Assigning the return value of new by reference is deprecated
The message will be repeated 20 times in the downward
Another thing my images which are cached from rss url is not displayed rather than in post thumbnail where I used to manually select image to my front page post image.
If anyone can help me I would be very grateful.
