- What widget update causes the problem?
The first one in the primary sidebar. The name is in French, but the translation would be : «old widget».
- What do you mean by updating the widget with a new date?
I just changed a little text displayed on the sidebar of my blog. It’s usually the date of my next text.
- Do you know what was the PHP version you had before?
I don’t remember, but I upgraded it the summer. As I’m not comfortable with those changes, I always stay very cautious. I use what is recommended.
- If you deactivate the show post plugin, does the error effectively goes away?
I did not test that yet.
- Have you tried deactivating the other plugins temporarily to see if another one is at fault?
I haven’t thought about that. I’ll try.
